Control with dynamic output-observer-feedback and stable transmission-zero compensator
基于稳定传输零点补偿器的动态输出观测器反馈控制

When a controlled system does not satisfy the sufficient conditions for dynamic output-observer-feedback control, we propose compensating the stable transmission-zero by connecting a cascade compensator to the controlled system. This configuration ensures the realization of dynamic output-observer-feedback control, and improves the robust stability of the closed-loop system. Experiment results show that the robust stability of dynamic output-observer-feedback control with a stable transmission-zero compensator is better than that with the full-order state-observer when the parameters of controlled system are perturbed.
