摘要 针对卫星天线定位伺服系统,提出了基于有限转角力矩电机(LATM)直接驱动伺服控制系统,并设计了一种简单有效的基于积分反推原理的伺服控制器,利用Lyapunov直接法稳定理论证明了系统的全局稳定性。通过数字仿真,验证了该控制器对外部扰动及系统参数变化具有较强的鲁棒性。 A nonlinear controller based on back-stepping control with integral function was designed. The overall stability of the system was proved using Lyapunov function. Simulation results for the servo-system show that this controller has strong robustness to external disturbance and system parameter changes.
