Nise Control Systems Engineering 6th solultions

Predictive direct power control (P-DPC) applied to voltage source pulse-width-modulation (PWM) rectifier was introduced in this paper. Based on the model of power prediction, voltage vectors were selected according to minimizing power errors in a fixed time interval, which results in a constant switching frequency control for P-DPC. It simplifies the implementation of P-DPC procedure by selecting switching states based on the principle of space vector modulation (SVM). In order to eliminate power errors caused by control delay, a detailed control delay compensation scheme was designed. Experimental results based on a 2kW prototype were presented, which showing that P-DPC has a faster power response compared to standard voltage-oriented-control (VOC) techniques. Besides, the dynamic performance of the system is also improved significantly by control delay compensation.
