| Abstract: | Aiming to overcome the weakness of PID controller,a excitation controller of voltage feedback and speed feedback was designed based on nonlinear tracking-differentiator.It is combined with chaos method and genetic algorithm,and tunes the parameters of NPID excitation controller by using the optimization algorithms.Simulation result shows NPID excitation controller can improve not only the voltage characteristic,the steady state stability and transient stability of power system,but also has the good performa... |
