Different approaches to the solution of the AGV transportation system control are presented in the paper. The first one is based upon the standard Petri nets extended for control. A way of the process control level modeling is shown. It is a basis for the control of the AGV system at the coordination level. An outline of the transportation co-ordination algorithm is described. Another approach is via supervisory control combined with a routing optimization algorithm. Then an approach using colored Petri nets is presented. All approaches are compared.

In this paper new necessary and sufficient conditions for static output feedback robust controller design for linear discrete time-invariant systems have been used. The output feedback robust controller design may be reduced to the problem of finding a feasible point under Biaffine Matrix Inequality constraint. In this paper the BMI problem of the output feedback robust controller design has been reduced to LMIs problem. The proposed LMI based algorithms are computationally simple and tightly connected with the Lyapunov function, quadratic stability, guaranteed cost and LQ optimal state feedback design. The structure of the output gain matrix can be prescribed by the designer.

The paper addresses the problem of design of a robust controller for a class of non linear uncertain systems to guarantee the prescribed decay rate of exponential stability. The polytope type bounded deterministic uncertainties are considered both in a studied system and its input part. The proposed approach does not employ matching conditions.

The paper deals with the design of decentralized robust controllers with output feedback for a class of interconnected linear continuous time systems with parametric uncertainties. The uncertainties, in general nonlinear, can appear both in the subsystems as well as in their interconnections. No matching conditions or other similar constraints are to be considered in the complex uncertain system model. The proposed two approaches have been verified on a design of decentralized robust PI controllers using non-iterative LMI based algorithm.
