| To deal with the lack of associated control between the excitation system and the speed system, we build the nonlinear mathematical model for the moving power station and propose the excitation and speed synthetic nonlinear robust control. The key state parameters of the mathematical model are estimated by the double strong tracking filter (DSTF). According to the exact feedback linearization and the nonlinear robust control method of the multi-input and multi-output system, the synthetic control law of the excitation and electro-mechanical speed control system is obtained by solving the linear matrix inequality (LMI), and is testified by simulation. Simulation results show that the DSTF can track and estimate the values of the state parameters rapidly when the load increased suddenly, and the nonlinear robust synthetic control not only can stabilize the excitation system and the speed control system, but also can realize the L2 disturbance
attenuation. |
