摘要
针对PID控制器对过载自动驾驶仪特性的影响,对带有PID控制器的双回路过载自动驾驶仪的工作原理及其特性进行了分析。分析表明,带有PID控制器的双回路过载自动驾驶仪可以使静不稳定弹体稳定,且对于不同的气动参数,其稳态输出不会受到影响。该自动驾驶仪对于舵机常值零位误差输入没有稳态误差,而经典过载自动驾驶仪对于同样的舵机零位误差输入则产生稳态误差。相比含有积分矫正的双回路自动驾驶仪,带PID控制器的双回路自动驾驶仪响应速度更快。仿真结果表明了本文理论分析的有效性。
Aiming to study the effect of PID controller on the characteristics of overload autopilot, the working principle and characteristics of the dual-loop overload autopilot with PID controller are analyzed. The analysis results show that the dual-loop overload autopilot with PID controller can statically stabilize unstable projectiles, and its steady-state output will not be affected for different aerodynamic parameters. Meanwhile,the autopilot has no steady-state error for the constant zero error input of the steering gear, while the classic overload autopilot produces steady-state error for the same zero error input of the steering gear. And comparing with the dual-loop autopilot with integral correction, the dual-loop autopilot with PID controller has a faster response speed. The simulation results show the validity of the theoretical analysis in this paper.
