Mathematical model and nonlinear control strategy of three phase voltage PWM rectifier

Based on basal mathematical model of three phase voltage pulse width modulation(PWM) rectifier,affine nonlinear model,Euler-Lagrange and port-controlled Hamiltonian dissipation model are obtained.Combined with nonlinear control theory,feedback linearization and passivity-based control(PBC) strategies in three phase voltage PWM rectifier are discussed.A review on the nonlinear control strategies of three phase voltage PWM rectifier is given.In order to implement superiority complementation,the combination of PBC with auto-disturbance rejection control is proposed.
