Zero Dynamics Analysis for Inverse Decoupling Control of Asynchronous Traction Motor
Considering the problem for inverse system method in EMU AC induction traction motor linear decoupling, the zero dynamics subsystem will be separated from the original dynamic system through coordinate transformation. Firstly, a getting method for zero dynamics of the multiple input multiple output nonlinear system is discussed when γ< n. Second,
