模糊PID控制器在微重力系统中的应用

为迭到吊丝随动系统的性能要求，根据拉格朗日方程建立系统四自由度动力学模型，提出实时改变量化因子以改善模糊PID控制算法，在此基础上加以仿真。通过实时对PID控制器的比例参数、积分参数、微分参数以及模糊控制器参数的在线调节，实现对系统响应曲线的优化。结果表明，该算法可以有效提高系统的反应速度，抑制超调，效果显著。

Application of Fuzzy PID Controller in Micro-gravity System

In order to achieve the request of silk free system,according to the Lagrange Equation,we build a 4 mechanical freedom dynamic modle,and put forward a way to improve the Fuzzy PID control arithmetic by real-time adjustment of parameters,we make simulation based on it. By the real-time adjustment of proportion parameter, integral parameter,differential coefficient and fuzzy controller parameter,we can optimize the response curve of system. The results show that the arithmetic can enhance the response velocity of system effficiently,and it can also restrain superscale prominently.
