In the voltage and current controller design, the paper take two different method: PID single-loop feedback and double-loop PI feedback, The parameter is still obtained by pole placement method. 在电压电流控制模块的设计中,分别采用了两种方法:PID单环反馈法和电压电流双PI反馈控制法,参数的求取依然采用极点配置法。
After analyzing various modulator structures, a single-loop third-order feedback structure combined with a one-bit quantizer is chosen to realize this modulator ultimately. 在对各种调制器结构进行分析后,最终选择了单级三阶反馈型结构结合一位量化器来实现。
The two modes of the control systems have been established and simulated in MATLAB/ Simulink. The simulation result shows: the dynamic performance of double-loop PI feedback is better than PID single-loop feedback. 在MATLAB/Simulink搭建了两种控制系统模型,并对其进行了动态仿真,分析比较后的结果表明:电压电流双PI闭环控制的动态性能指标优于PID单环。
To enhance system stability, this paper has introduced a single-loop voltage PI positive feedback and double loop PI control of voltage and current, Simulation results demonstrate the feasibility of this method. 为提高系统的稳定性,本文先后引入了单环电压PI的正反馈和电压电流双环PI控制,仿真结果验证了此方法的可行性。
