| Abstract: | The nonlinear control of a BUCK converter with constant power loads is studied.According to the nonlinear characteristic of constant power loads,a nonlinear stabilizing controller based on exact feedback linearization technique is proposed.The SABER is used to simulate the control law.The simulation results show that exact feedback linearization technique can be used to control a DC/DC converter supplying constant power loads.During large disturbances in the power supply and the loads,the nonlinear controll... |
