自抗扰控制器利用跟踪微分器可解决超调量及快速性之间的矛盾,分数阶PID控制器在提高控制品质的同时扩大了被控系统参数的稳定域.结合自抗扰技术及分数阶PID控制器设计了自抗扰分数阶PID控制器,并应用于高超声速飞行器再入姿态控制.仿真结果表明,自抗扰分数阶PID控制器对于高超声速飞行器非线性模型及强外干扰的影响下具有很好的控制效果,并且有较大的稳定域,即针对被控系统参数变化具有更强的鲁棒性.

Active disturbance rejection controller (ADRC) uses tracking-differentiator (TD) to solve the contradiction between the overshoot and the rapid nature.Fractional order proportion integral derivative (PID) controller improves the control quality and expands the stable region of the system parameters.ADRC fractional order (ADRFO) PID controller is designed by combining ADRC with the fractional order PID and applied to reentry attitude control of hypersonic vehicle.Simulation results show that ADRFO PID controller has better control effect and greater stable region for the strong nonlinear model of hypersonic flight vehicle under the influence of external disturbance,and has stronger robustness against the perturbation in system parameters.
