零极点偶配置在横向自动驾驶仪设计中的应用

The Use of the Zero and Pole Pairs Method in Lateral Autopilot Law Design

系统特性主要取决于系统闭环传递函数中零极点的分布。采用零极点偶配置法，将零极点合理地配置在理想位置，不但能使系统简化，降低其价次，而且可以改善系统性能，使系统满足各方面的指标要求．现以某飞行器横向自动驾驶仪控制律设计为例，介绍了这一方法的应用，并根据所获得的控制律进行了数字仿真。仿真结果表明系统具有良好的动态响应特性，零极点偶配置法是方便可行的方法。

The system characteristics are mainly determined by the position of zerosand poles of the closed-loop transfer function. Therefore, matching the zero and polepairs reasonablly and ideally not only simplifies the system design and decrease the system order, but also improves the system qualities and satisfies a variety of requirements. This paper applies this method to control law design of an aircraft lateral autopilot and performs digital simulation according to the obtained control law. The simulation results show that the closed-loop system possesses good transient response andprove that this method is feasible.
