This paper focused on for the stability of SPWM inverter affected by digital control. The stability of analog control inverter system, discrete system with no-step-delay control and discrete system with one-step-delay control are analyzed respectively so as to determine the relation of the inverter's sampling period vs. controller parameters with critical stability. Then the essential reason was analyzed...
This paper focused on the research on one-step-delay effect of the stability of digital control PWM Inverter. Discrete stability criterion is used to research the stability of discrete system with/without one-step-delay control respectively. The research results are shown that the one-step-delay control degrades the stability system in the high sample frequency while it may increase the stability...
Compared with analog control, digital control adopted in PWM inverter possesses the evident advantages but the traditional PID control strategy which is realized in digital method often can't achieve better performance than in analog control. In past references, there is hardly quantitative analysis on the effect of digital process on the performance of PWM inverter. This paper did a creative research...
The traditional PID control strategy which is realized in digital method canpsilat achieve better performance than that in analog control. The reason was analyzed why the digital process influences the digital controlled PWM inverterpsilas 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...
The repetitive control technology is a high cost-performance waveform control technology widely used in the control of inverter. Compensator as the key parts of repetitive controller is usually adopted as the combination of notch filter with second-order filter. The process of designing and debugging of the repetitive controller, which needs more experiences, is very tedious. In this paper, FIR (finite...
