title = "The research on the digital controlled effect of performance on the PWM inverter",
abstract = "The traditional PID control strategy which is realized in digital method can't achieve better performance than that in analog control. The reason was analyzed why the digital process influences the digital controlled PWM inverter's performance in this paper. One is the process of the zero-order hold. Another one is one-step-delay control which is usually adopted in digital control. Three aspects were analyzed in which influence the digital controlled PWM inverter's performance: (1) how the process of zero-order-hold effects the open-loop frequency property of the digital controlled inverter system (2) how the process of zero-order-hold effects the system's stability (3) how the one-step-delay control effects the system's stability. On the base of setting up discrete mathematical model of the digital controlled inverter system, theory deduction and simulations were done in the condition of P regulator Relevant experiments verify the rightness of the analysis and direction for the design of the digital controlled PWM inverter were given. Finally relevant experiments verify the theoretical analysis.",
