摘　　要：基于反推控制理论对飞控系统舵回路进行设计。针对舵机内部参数的不确定性和外部负载力矩的扰动,在构造辅助控制输入时引入积分环节。通过适当选取李雅普诺夫函数,使分步构造的控制输入信号有界,并确保角位置跟踪误差能从所有可能的初始状态收敛。数字仿真结果表明,该设计方法增强了舵回路的鲁棒性并提高了稳态控制精度。The actuator servo system was designed based on backstep. An integral was integrated in the backstep. The system robustness against modeling uncertainties and external disturbance was improved by the added integrator. Lyapunov function was utilized by backstep control to guarantee the convergence of the position tracking error under all possible initial conditions and the boundedness of all input signals. Digital simulation results show that this method improves the system robustness and steady-state control accuracy.
