The major objectives of the paper are to propose a torque based control method of the whirling motion under mechanical resonance and to confirm the effectiveness of our method experimentally. The torque is controlled to suppress the whirling motion instead of using the electromagnets that are required in some conventional control methods. The control input is determined based on a sufficient condition for stability in a system represented by a second-order vector differential equation whose coefficients are continuous, bounded, and time-varying matrices. The effectiveness of our control method is discussed by both a simulation and an experiment.

Simulation plays a key role in functional design, virtual prototyping, re-engineering and manufacturing supervising. The detailed simulation of driving an entire vehicle and its environment includes a driver model. In the paper the design of a driver model is presented. It is capable of dealing with different car models and the whole variety of real roads. Above all, it can be adapted to the wide range of human behaviour, including experienced test driving.

In many process control applications, a single controller design algorithm can not give optimal performance for a wide range of plant structures and operating conditions. In the paper, an adaptive multi-class controller is introduced. Two online identification algorithms run in parallel in the proposed controller and the one with least error cost function value is selected. According to the parameters and structure of the selected estimated model, a controller selection rule-base is developed. Experimental studies are included to demonstrate the performance of the proposed multi-class controller.

An ant system (AS) algorithm is introduced into an optimization problem solving in a continuous field. A corresponding algorithm is defined and good simulation results are derived in examples of the global optimum value searching of a multi-minimum continuous function and a nonlinear continuous function.

The problem considered addresses the optimal wastewater distribution to several retention reservoirs in an urban sewer network during rainfall in the aim of protecting the quality of waters that receive the network outflows. The main task of the corresponding control system is the minimization of overflows during rainfall events. The proposed solution of this complex control problem employs nonlinear constrained optimal control concepts while the rolling horizon method is used for the real-time application of the optimal control algorithm with updated inflow predictions and updated initial conditions. A detailed study of the control problem for a particular large-scale real combined sewer network using this method is presented on the basis of a realistic simulation model. Results demonstrate the efficiency of the developed methodology as well as its low sensitivity with regard to modeling and prediction errors.

This paper presents the optimal nonlinear filter for a stochastic system state given by a polynomial equation of degree 3 or 4 and linear observations confused with white Gaussian noises. The obtained filtering equations are applied to solution of the state estimation problem for a nonlinear automotive system. Simulation results are compared for the optimal polynomial filter given in this paper and the linear Kalman-Bucy filter applied to the linearized system.

This paper presents the closed-loop composite control of singularly perturbed bilinear systems with a quadratic performance criterion, using the successive Galerkin approximation (SGA). The singularly perturbed bilinear system is decomposed into two subsystems of a slow-time and fast-time scale by the singular perturbation theory, and we obtain feedback control laws from each subsystem using the SGA. We design the composite control law that consists of two optimal control laws for each subsystem. This paper attempts to design the closed-loop composite controller of singularly perturbed bilinear systems with the SGA method, and to reduce the disadvantages of the SGA method.

The design of the positioning controllers in optical disk drives are today subjected to a trade off between an acceptable suppression of external disturbances and an acceptable immunity against surfaces defects. In this paper an algorithm is suggested to detect defects of the disk surface combined with an observer and a linear quadratic regulator. As a result, the mentioned trade off is minimized and the playability of the tested compact disk player is considerably enhanced.
