Analysis and simulation to the static and dynamic characteristics of the EMS control system

The inherent unstability and nonlinearity of the EMS system made it difficult to design a controller to maintain the airgap at a steady value. The authors analyzed the static and dynamic characteristics of the EMS system and simulated it on MATLAB with nonlinear and linearized model. The results show that the controller that based on the linearized model of the large airgap has low overshoot,static error and fast response.
