The adaptive inverse model controller for new system of DC-DC converter for rolling stock auxiliary power supply

A DC-DC power converter for rolling stock auxiliary power supply applications has nonlinear characteristics such as variation in HV DC source, imperfect characteristic of component or material, duty-cycle varying harmonics characteristic and load variations that cause perturbation in the controlled system. An adaptive inverse model controller (AIMC) is used to overcome all of these problems. The adaptive system control law uses the least mean square algorithm.
