摘 要: | 讨论了采用晶体管PWM放大器的炮瞄随动系统的设计方法,根据系统处于失调状态时的最优速度运行曲线和相轨迹,结合典型系统的设计方法提出一种新的调节器形式及参数计算方法,并依不同运行情况采用不同的控制模式,从而保证系统有良好的快速性及高抗干扰能力,配炮运行结果表明:所设计的系统对任意误差协调无振荡、无超调,对斜坡、正弦等任意输入都具有良好的跟踪性能。

Abstract: | The design of a servo system for cannon aiming adopting the PWM amplifier is de-scribed.Based on the operating characteristic at optimal speed and phase trajectory,a newregulator model and its parameter calculation are proposed in connection with a typical sys-tem design. Different control strategies are adopted according to different operating condi-tions so as to guarantee a high speed response and robustness. Test results show that thesystem operates with excellent performance. |
