控制系统最速响应鲁棒性设计

为了简化实际中控制系统鲁棒性的设计,提出一种有约束多目标最优化的鲁棒性时域设计方法。该法先对名义值系统进行设计,把自动驾驶仪的上升时间转化为目标函数,将系统超调量、稳态误差等性能指标转化为约束条件,采用有约束最优化方法设计名义值系统的控制器;然后考虑系统的鲁棒性,将参数的波动范围转化为对象族,采用优化方法设计出对象族的控制器,即考虑了系统的鲁棒性,通过仿真证明该算法是可行的。

Control system fast response robustness design

To simplify the robustness design of missile autopilot,an optimization method in time domain is proposed.At first the nominal system is designed,the rise time is translated into objective and the overshoot and the steady state error are converted into constraints,then the optimization method is used to find the controller.Then in the robust design period,the parameter change is translated into a group of objects,and then the robustness design problem is solved by multi-objective optimization method.The simulation proves that this method is feasible.
