摘　　要：针对坦克炮控系统中同时存在齿圈间隙、摩擦力矩和参数漂移等多种非线性因素,造成系统驱动延时、换向振荡和低速"爬行"等问题,从分析系统的各种非线性特性及其影响入手,建立了包含多种非线性在内的炮控系统数学模型。在此基础上,借助"系统总扰动"的思想,引入自抗扰控制技术,采用"跨阶控制"方案,实现了系统的非线性补偿控制。仿真表明,所设计的控制器能够同时有效地抑制了各种非线性因素的影响,很好的改善了系统性能。Aiming at the problems of system drive time-lapse,commutation surge and dithering on the low velocity caused by nonlinearity such as backlash,friction and varieties of system parameters,the nonlinearity was analyzed and the math model of gun control system was built.On the basis of that,the strategy of ADRC was brought forward by dint of the thought of ＇system＇s all disturbances＇,and the span-rank control was adopted.Finally,the compensation control of nonlinearity was implemented.The simulation result shows that the influences caused by the diversified nonlinearity are restrained and the system performance is improved soundly.
