A method for fault detection and identification in control system under external disturbance and variations of plant parameters is presented.
提出了一种在模型参数变动和存在外部扰动条件下的控制系统故障检测与识别方法。
The method has the advantage of easier calculation than normal ones. When the plant parameters change within a certain range, it can still work well.
本方法比通常自校正内模控制算法的运算量大大减少，而在对象参数在一定范围内漂移时，同样能取到自校正效果。
The asymptotic tracking or the attainment of zero tracking error in the steady-state which is robust with respect to the plant parameters can be accomplished with the robust two DOF.
鲁棒二自由度控制结构还能实现对于对象参数具有鲁棒性的稳态零误差跟踪。
