ROBUST OPTIMAL DESIGN OF THE SYSTEM WITH L₂ BOUNDED UNCERTAINTY UNDER REGIONAL POLE CONSTRAINT

The paper investigates the selection of weight matrix in LQL index for optimization of uncertain systems with L₂ bounded uncertainty while satisfying the regional pole constraint. Based on the given robust optimal pole placement region, the constructive equation for the weight matrix Q is presented. In this case, the robust optimal design is achieved with the stability margin. The illustrative example demonstrates the effectiveness of the method.
