以坦克水平向火控系统为对象 ,采用滑模变结构控制 .在性能指标优化的前提下完成切换函数的计算 ,并采用单位向量法 ,实现了全新的炮控系统设计 .用该方法设计的控制器只含一个非线性环节 (即切换函数只有一个 ) ,因此切换函数易于连续化 .以MATL AB语言为基础得出的仿真结果表明 ,用该方法设计的稳定器稳定精度比性能指标要求的精度提高了 33倍 ,比经典方法提高 2 31倍 .取得了满意的控制效果 .该方法同样适用于导弹和其它飞行器自动驾驶仪的设计
In order to control the fire control system at the tank level, the sliding mode variable structure control is adopted, the switching function is calculated under the premise of the performance index optimization, and the new vector control system design is realized by using the unit vector method. The controller has only one non-linear link (that is, there is only one switching function), so the switching function is easy to be continuous.The simulation results based on MATL AB language show that the stability of the stabilizer designed by this method is better than the performance index The precision is improved by 33 times, which is 2 31 times higher than the classical method, and the satisfactory control effect is achieved. The method is also applicable to the design of the autopilot for missiles and other aircraft
