摘　　要：采用基于标准特征多项式的飞控系统设计方法设计了某型飞机横侧向通道倾斜姿态保持和航向保持控制律,并进行了仿真研究。控制律的设计过程和仿真结果表明,该方法可以确切地给出系统的过渡过程时间和超调量,避免了任意选择初始参数值的盲目性和经验性,大大简化了飞控系统设计的工作量。Flight control system design method based on standard characteristic polynomial is used to design the lateral bank attitude hold and heading hold control laws of an aircraft.Some simulation results are given.The control law design process and simulation results show that the standard characteristic polynomial method is an effective,simple and intuitional way for the design of flight control systems.It can let you know tuning time and overshoot of a system before designing a control system,and reduce the calculation loads.
