In this paper, a back-to-back PWM converter is considered as the optimum scheme of ac excitation power supply and its operation principle and controlstrategy are discussed in detail.
The control system reaches the optimum by choosing the right control algorithm and control strategy.
通过选择合适的控制算法和控制律,使控制系统达到优化。
