Abstract：This paper gives a new adaptive PID controller named X-Q. It has novel frequency characteristics of adaptability: For the control action it is an adaptive PID controller without any phase lag, but there is an amplifier with the gain k in the high frequency and an integrator with integral time constant τ in the low frequency; For the harmonic input it is still an adaptive PID controller, but the transfer function in the high frequency is W=0.81ke-j51.85°, the transfer function in the medium-low frequency is( ). Finally, employ the new adaptive PID controller to realize satisfied control of the multiobjective control system(MOCS). The results show that its performances are much better than the ones of ITAE optimum control system.
