Abstract

For improving the tracking performance of the general motor servo systems with quantized control input and disturbances, a new quantized funnel control strategy is proposed. A new simple virtual output is introduced to address the high relative degree problem in the applications of funnel control, and the tracking error will be also prescribed in a funnel region. This strategy removes the complex design of funnel controller in systems of relative degree two. In addition to, the unknown system states and disturbances are estimated by an extended state observer, and the quantization error is compensated. Then, the stability of the closed-loop control system is guaranteed by the Lyapunov theory. Some simulations illustrate the effectiveness of the proposed control strategy.
