飞行器姿态控制系统中的一种计算机仿真研究

针对飞行器姿态控制系统的参数时变性和不确定性干扰等特点，本文给出了一种基于Ackermann规则的滑模变结构控制器，并在设计滑模面时，引入积分项来消除干扰等因素给系统带来的稳态误差；为消除抖动，在控制器中引入模糊系统来实现去抖；同时设计灰色补偿控制项来抵消不确定项对系统造成的不利影响。最后进行了计算机数字仿真，结果表明本文所设计的控制器具有很好的效果。

Fuzzy Integral Variable Structire Control for Aerocraft Attitude-Control System

Because the parameters of the aerocraft attitude-control system is changing and the uncertain disturbance is existing all the time. This paper designs one variable structure controller （VSC） based on Ackermann＇s regular. Designing the sliding function, adopt the integral to eliminate the steady error. Adopt the fuzzy system to ehminate the chattering of system. And design the grey compensator to eliminate the bad influence of incertitude. The result shows that the controller has the good effect.
