摘要
针对控制力矩陀螺框架伺服系统传统PI控制对干扰、负载变化等不确定因素的控制能力不足,设计了模糊PI控制器,利用参数自整定速度控制器实时调整参数,实现了框架伺服系统的高稳定性控制.仿真结果表明,相比传统的PI控制策略,响应快,超调小,无需修改参数,有更好的动静态特性,能更好地满足控制力矩陀螺框架伺服控制系统的鲁棒性要求,并有很好的跟踪性能.
The control capability of gimbal bal control moment gyro （SGCMG）. This servo system is one of the key characteristics of the single gim-paper introduces a control system based on Fuzzy PI controller. Considering the drawbacks of the traditional PI controller, we design a fuzzy control algorithm with param-eter self-tuning capability based on fuzzy control technology. Simulation results show that the proposed control strategy has faster response than the traditional ones. Meanwhile, the overshoot is smaller and it has no parameter tuning requirement. Besides, the proposed controller is robust and has excellent track-ing capability.
