摘要：
This study suggests a proportional-type output-voltage control algorithm of a three-phase inverter for uninterruptible power supply applications with performance-recovery and offset-free properties. It makes the two contributions. The first one is to introduce first-order disturbance observers (DOBs) so as to exponentially estimate disturbances originating from model-plant mismatches. The second one is to rigorously prove that the proposed proportional-type feedback-linearising controller equipped with DOBs guarantees performance-recovery and offset-free properties. The experimental results conducted in this study, which uses a 10 kW three-phase inverter with an output capacitor, confirm that the closed-loop performance is satisfactory in both transient and steady-state periods.
