摘要:
针对 PWM 整流器在传统双 PI 控制中存在非线性、高次谐波和抗扰性差等缺点,以三相电压型 PWM 整流器为研究对象,提出了一种单神经元自适应 PID 与传统 PI 复合的新型控制策略。以电压外环误差限作为调节器切换依据,在误差限值以上利用神经元自学习、自整定算法输出动态可变的 PID 参数调节电压,在误差限值以下采用 PI 调节器快速减小静差,同时在电流内环引入前馈解耦策略实现电压、电流双闭环控制。对系统进行了仿真实验,结果表明这种控制方法能有效改善电压的抗扰性和电流的跟随性,提升电能质量并减小谐波污染,系统动静态性能良好。
Abstract:
Aiming at the disadvantages of nonlinearity , high-order harmonics and poor immunity of PWM rectifier in traditional double PI control , and taking three-phase voltage source PWM rectifier as the research object , a new control strategy based on single neuron adaptive PID and traditional PI is proposed. Taking the error limit of the outer voltage loop as the switching basis of the regulator , the neuron self-learning and self-tuning algorithm is used to output dynamically variable PID parameters to regulate the voltage above the error limit , the PI regulator is used to quickly reduce the static error below the error limit , and the feedforward decoupling strategy is introduced into the inner current loop to realize the double closed-loop control of voltage and current. The simulation results show that this control method can effectively improve the voltage immunity and current following , improve the power quality and reduce the harmonic pollution. The system has a good dynamic and static performance.
