Summary: One approach to the nonlinear-system design using
thesimultaneous stabilization method and parameter optimization isgiven and
demonstrated on one example. Quasi-linearization ofnonlinear system, using
frequency response and time response, issuggested. The structure and
starting parameters of thelinearized model are based on the frequency
response while thetime response of the nonlinear system have been used for
fineparameter tuning. Because the system behaviour depends on
someproperties of the input, linearization has been performed fordifferent
forms of input signal. Using linearized models,simultaneous stabilization
and parameter optimization method forcontroller design is performed. It is
shown that obtaindcontroller improves system dynamics for the given range
of inputsignals. The method was tested on one example. Obtaind
resultsclearly indicate its efficiency.

Summary: An adaptive procedure, used for the simulation of stiff
systems,which maintans simulation stability for a time-varying
linearsystem, is presented. A recursive least squares algorithm is usedto
estimate the system eigenvalue, and the Stability RegionPlacement (SRP)
design method is used to determine thecoefficients an explicit linear
multistep integration operator.Results are given for different types of
inputs and variationpatterns for the eigenvalue. It was shown that the
proposedmethod is able to cope with slowly varying parameters of thesystem,
which makes this method a possible choice for theimplementation in those
control structures which use the model ofa proces.

Summary: The paper presents a synthesis of a nonlinear ship
steeringcontrol system through application of the simultaneousstabilization
and parametric optimization methods. The shipsteering control system is
closed through the gyrocompass andautopilot. The loop consists of an
autopilot, the steering gearsubsystem, and a ship. For linearization of the
nonlinearsteering gear subsystem the procedure of quasi-linearization
isused. The steering gear linearized model structure and initialparameters
are determined by means of frequency characteristicsof the steering gear
subsystem, while the time response isutilized for the fine adjustment of
parameters. The dynamics ofthe ship. treated as a linear part of the
system, variesdepending on conditions (trim, depth etc.) to which the ship
issubjected, and can be described by a set of transfer functions.The
linearized steering gear model together with a set of theship linear models
produce the nonlinear ship steering controlsystem model with variable
parameters. The obtained modelconsists of a set of transfer functions
describing the completesystem dynamics in open loop. After obtaining such a
model of thesystem, an autopilot design is taking place by applying
thesimultaneous stabilization procedure. The obtained regulatorstabilizes
the system under given operating conditions,respectively, it stabilizes the
set of transfer functions. Theprocedure of parametric optimization of the
nonlinear system withvariable parameters is used to improve the system
dynamics,whereas through the simultaneous stabilization procedure only
thesystem stability conditions are checked. The procedure isverified, and
the obtained results confirm the advantage of theautopilot obtained in such
a manner.

Summary: By means of the technology applied until lately and with
theshipboard energetic processes control systems configurationspossible in
this connection it was nearly impossible to organizethe process management
and graphic presentation of processingstates. The process management was
present in fact, but onlythrough operator who, thanks to the aggregate
knowledges aboutsingle functional block (energetic subprocess) and
mutualorganization of subprocess, was enabled in a major or minorextent to
perform the management of the shipboard energeticprocesses. Also, the
interactive interfaces in classical formbecame the bottleneck of
communication with process. It is notpossible to menage the process without
perfect comunication orpresentation respectively. Through appearance of new
technologiesalso quite new process organization forms imposed themselves
asfeasible, receiving on them the majority of process algorithmsand
enhancing in this manner the total efficiency and safety ofthe process as
well of the ship in its entirety.

Summary: A new technique for control system design based on the
Optimal Constrained Covariance Control (OC3) is presented. A design
procedure of control system for dynamic ship positioning is proposed. In
the papers published so far the controller gain matrices were determined
using the classical Linear Quadratic Gaussian (LQG) optimal control
technique, the pole-placement technique and characteristic locus design
method. The main disadvantage of these techniques is their poor
correspondence with the real performance requirements of control system.
Using the proposed technique this disadvantage is avoided. The results of
computer simulation using OC3 control are presented.

Summary: Algorithm for the identification of multivariable linear
time-invariant system is presented. Algorithm is inspired by the
geometrical picture of a matrix, and leeds to state-space model. Two block
Hankel matrices are built from limited number of i/o data, and consequently
a state sequence is realized as the intersection of row vector subspaces of
these Hankel matrices. System state matrices are obtained from the
overdetermined set of linear equations using least squares method. Use of
reliable SVD (Singular Value Decomposition) provides numerical stability
even in the case of very noisy i/o data and reduces matrix computational
load.

Summary: The new predictive PI+D autopilot is proposed for a ship
course-keeping control system. The control system consists of the ship,
steering gear system and autopilot. The steering gear consist of the rotary
power unit where the servo is aproximated with a relay with daedband and
hysteresis, and a servo actuator with main pump modeled with ratelimited
servoactuator. Because it is known that the linear treatment is effective
for prediction of lateral motion in waves during course keeping, the ship
is treated as the linear one, with three degres of freedom. Simulation
study confirmed that the predictive PI+D autopilot should be recommended
especially when tuned to minimize rudder activity and heading error.

Summary: In the paper the comparison of the conventional PID
autopilot and newly proposed predictive PI+D autopilot is given. Both
autopilots were investigated by simulation. Ship's course-keeping control
system consist of the ship, steering gear and autopilot. The steering gear
consist of the rotary power unit where the servo is approximated with a
relay with deadband and hysteresis, and a servo actuator with main pump
modeled with ratelimited servoactuator. Because it is known that the linear
treatment is effective for prediction of lateral motions in waves during
course keeping, the ship is treated as the linear one, with three degrees
of freedom. The coefficients used are based on captive model test results
for a 250000 DWT at an operating speed of 15 knots in fully loaded and in
ballast condition, and of the high speed containership at 32 knots.
Simulation study confirmed that the predictive PI+D autopilot should be
reccomended. Autopilots are compared for the full and ballast tanker, as
well as for the containership. Predictive PI+D autopilot is tuned to
minimize rudder activity and heading error. Reccomandations for tuning
predictive PI+D autopilot for various ships are given in the paper.

Summary: The design of the simultaneous stabilizable autopilot is
presented. This autopilot has the capability to simultaneously stabilize
more than one ship's mathematical model, which is valid for particular
operating condition. Moreover, designed autopilot not only stabilizes the
system under given operating conditions, but also ensures desired dynamic
response. The procedure of parametric optimization of the nonlinear system
with variable parameters is used to improve the system dynamics, whereas
through the simultaneous stabilization procedure the system stability is
ensured. The procedure is veryfied, and the obtained results confirm the
advantage of the autopilot obtained.
