Abstract

In this paper, a hybrid PI (proportional integral)/LQR (linear quadratic regulator) control method for STATCOM (static synchronous compensator) control is introduced. The control logic is evaluated in Matlab/Simulink, and the simulation results are compared with those coming from the traditional PI control design. It is shown that the new method is superior to a PI method in both design complexity and response performance. The new method generates less oscillation and has shorter settling time.
