Research on Μ Synthesis Based Hydroturbine Governor Design
نویسندگان
چکیده
A novel hydroturbine governor scheme based on networked control system (NCS) is proposed. The key problem of the scheme rest with the time delay existing in the data communication in NCS as the time delay may be a detriment to governor system stability and may degrade system robustness. In order to guarantee the governor system stable with time delay, the uncertain delay model is modeled as multiplicative perturbation, and a μ synthesis based robust governor is presented. The result verifies feasibility of the robust controller.
