Abstract

An optimal control algorithm with adaptive system parameters and state variables estimation is presented in this paper. The optimal control algorithm is calculated by solving the algebraic Riccati equation of the linearized closed loop system model obtained by using an adaptive recursive least squares identification algorithm. The feedback control is achieved by recalculating the control sequence each sampling period. An application of the algorithm as a power system stabilizer is illustrated
