Optimum Control of Electrical Drives and Power Converters

Beschreibung

This work belongs to the optimization of control methods for power converters and electrical drives. Main contributions are as follows: an analytical solution of both continuous and discrete optimum control for power converters and drives is given, focusing on computational efficiency and enhanced performance; a new DC-link voltage balancing method using the deadbeat control concept for three-level NPC converters is proposed, which is suitable for the control applications using space vector modulation; a simple and effective neutral-point voltage balancing technique is proposed within the model predictive control framework for three-level NPC converters, which decouples the neutral point voltage balance control and targets current tracking; a fixed gain filter is proposed to estimate the position, velocity, and acceleration in angular motion, with computational efficiency and less tuning effort.
