English Abstract

In this thesis, a new technique for control system design is developed. It consists of two sptes: 1) design of an H°° statefeedback conrol law; 2) recovering the achievable performance using a state observer. The resulting controller will ensure internal stability andunder certain conditions minimizes the H°° norm of the closed-loop transfer function. The controller computations will reduce to solving one algebraic H°° Ricatti equation compared to two algebraic H°° Ricatti equation using the H°°design method. For discrete time systems, a recovery procedure for the LOG/LOR method using current estimator for compensators with large processing time is introduced. A simplified LOG/LTR frequency domain design method for SISO discrete time minimum phase systems is developed. For this method, it is shown that the controller computations will reduce to selecting the zeros of the controller, and the poles of the controller will be the same as the zeros of the plant. Several design examples are used to illustrate the theoretical developments of this thesis.
