【Abstract】 It is still an open problem to eliminate the undershoot caused by zeros in the right-half plane of non-minimum phase systems (NMPS). To decrease overshoot, undershoot and settling time of NMPS simultaneously, this paper reasonably combines the parallel search structure of genetic algorithm with the controllable jumping property of simulated annealing to propose a hybrid strategy for designing a class of PID controller. Numerical simulations based on typical systems demonstrate the effectiveness and the adaptability of the hybrid strategy on NMPS, as well as the superiority of the designed controller.更多还原
