The main theme of this paper is to propose a self-commissioning technique for high bandwidth servo drives. The presented self-commissioning technique include auto-identification of servo motor parameters and on-line calculation of controller gains of servo drives. The electrical parameters required for current controller, including stator resistance and inductance are identified under standstill....
The main theme of this paper is to present the digital controller design of a power converter with predictive peak current-mode (PCM) control and leading-edge modulation. The advantages of the control and modulation technique include the reduction of the sampling frequency of the A/D converter, no need of slope compensation, and the provision of a fast dynamic current response. The discrete-time model...
Due to the merits of flexibility, reduction of analog components and no aging issue of external components, digital-controlled power converter becomes very promising. It is required to derive the discrete model of power converter for digital-power control. The effect of sampling frequency of A/D converter on the digital-controlled power converter is also very essential to the performance. The objective...
