Adaptive Disturbance Rejection Control of Linear Time Varying System
A novel adaptive disturbance rejection control scheme for a linear time varying (LTV) system from the perspective of differential algebraic framework is proposed. A numerical differentiator is used to obtain the derivative estimates from the system output, which contain overall dynamics of the system. Combining a local modeling technique and conventional proportional integral differential controller, the proposed control scheme perfectly accommodates disturbances and measurement noises. The convincing simulations validate the proposed control scheme well.
