Parameter Space Design of a State Predictive Controller Satisfying Robust Performance

摘要

Robust performance condition is an important measure for closed-loop performance. A parameter space design method of a three terms state predictive controller is proposed for plants described by a second order system with time-delay. The boundaries of two permissible regions of state feedback gains and observer gains that satisfy the robust performance condition are obtained, respectively. An appropriate gain can be found by drawing the regions on the two parameter planes, alternatively.
