Abstract :
An exact nonlinear multiple-input multiple-output (MIMO) state space mathematical model of the power circuit of pulse-width-modulation (PWM) three-phase three-level neutral point clamped AC/DC rectifier was developed. Using this nonlinear model, an input/output feedback linearization was then designed. Analytical expressions of the linearizing control law (LCL) were derived. The resulting linearized model is simply a decoupled linear system equation. Linear state feedback control law is then applied based on a pole placement strategy. Computer simulation results are presented to verify the effectiveness of the proposed closed loop system
