Most industrial processes are nonlinear. In such a case only a nonlinear model valid for the whole working area can ensure a good controller design. The nonlinear process is approximated by a multi-model consisting of...

We introduce a new, simple and efficient evolutionary algorithm to multiobjective optimization problem, which based on neighborhood and archived operation (NAGA). The innovations contain two main parts: neighborhood i...

For predictive control in industry often very long horizons for control error and manipulated signal are used because of the slow processes which take place in the petrochemical industry. In order to reduce the comput...

The paper presents a control system design technique in delta domain for IMC (Internal Model control) structure. Also a generalised form for delta domain Dead-beat control algorithm is given, a hybrid implementation o...

Tracking feedback control trade-offs increase dangerously with arbitrarily large uncertainties in the process mode!. This is shown by the bounds in the QFT domain. In this context, the paper develops a theory on the c...

When the process uncertainty size increases, even linear minimum phase systems must sacrifice desirable aggressive feedback control benefits to avoid an excessive 'cost of feedback', while preserving the robus...

This paper presents the current work on the development of a tool for remote control of mobile robots. The tool consists of a local controller on the robot side and a user interface for simulation and remote control that connects with the robot through the network. The user interface is implemented as an HTML page with a Java applet for remote control and communication and a virtual environment written in VRML for visualization. This way users have the ability to connect to a dedicated WWW server and download the user interface. This paper describes the concept of the tool design and the developed user interface.
Hybrid dynamic systems include both continuous and discrete state variables. Properties of hybrid systems, which have an infinite state space, can often be verified using ordinary model checking together with a finite...

A control systems engineering approach, employing a two-level overall system architecture and different but compatible formalisms for system representation on the upper and lower levels, has been investigated in detai...

The high practical significance of the I 1 T d -plant approximations has been shown by the perhaps most frequently used method for controller tuning by (Ziegler and Nichols, 1942), modified later for sampled data systems by (Takahashi et al ., 1971) and by many other authors. This paper extends previous works by developing plant approximations based on the single and double integrator models with dead time. These approximations are then used for tuning of the minimum time pole assignment P- (PD-) controllers designed for single (double) integrator with constrained input.
