This paper proposes a procedure for a robust decentralized controller design based on solving robust control design problems of subsystems' size. To consider the interactions in subsystem controller design, the appropriate interaction measure is discussed and a possible solution is proposed. The resulting decentralized control design scheme including input constraints is illustrated on the laboratory plant of two interconnected DC motor system. Simulation shows successful results for the designed decentralized robust stabilizing PI controller with input constraints.

This paper proposes a combined power quality-optimal control of the three-phase grid connected power converter. By using the technique of decoupling control, the mathematical model of the three-phase power converter is developed in the dq rotating reference frame and it is linearized around the operating point. The optimal control problem is with free-end point, infinite time horizon, and without constraints. The proposed optimal control is obtained as a solution of the Algebraic Riccati Equation. The numerical simulations based on the Matlab/Simulink software show the validity of the proposed solution.

The paper deals with the multimodel and robust control system design and their combination based on M − Δ structure. controller design will be done in the frequency domain with nominal performance specified by phase margin. Hydraulic turbine model is analyzed as system with unstructured uncertainty, and robust stability condition is included in controller design. Multimodel and robust control approaches are presented in detail on hydraulic turbine model. control design approaches are compared and used for derivation of new approaches which combine advantages of both.

Gain scheduling (GS) is one of the most popular approaches to nonlinear control design and it is known that GS controllers have better performance than robust controllers. Following the terminology in controlengineering linear parametervarying (LPV) systems are time-varying plants whose state space matrices are fixed functions of some vector of varying parameters. Our approach is based on considering the LPV system and scheduling parameter and their derivatives with respect to time are supposed to lie in a priori given hyper rectangles. For guarantee the performance we use the notion of guaranteed cost and optimised to given a cost function. The class of control structure includes decentralised fixed order output feedback like PID controller. Numerical examples illustrate the effectiveness of the proposed approach.

The paper deals with the parameter identification of nonlinear dynamic systems using three-block cascade models with static input and dynamic output nonlinearities. Multiple application of a decomposition technique provides an output equation for the corresponding nonlinear model description that is linear in parameters but includes more internal variables. An iterative technique allows estimation of all the model parameters and all the immeasurable internal variables based on measured input/output data. An illustrative example is included.

This paper proposes an approach to a robust PI controller design for real uncertain Coupled-Tank process in time domain. Only the first independent tank is considered (single-input single-output system). Polytopic model of uncertain system is considered as a plant model to be controlled. Stability and performance of the closed loop system is determined through the LMI region, where the closed loop poles of whole uncertainty domain are placed. A robust stability condition based on the parameter-dependent Lyapunov function (PDLF) is used.
