摘要
系统采用自适应模糊PID控制技术,针对串联谐振全桥逆变电路,利用MATLAB建立了系统自适应模糊PID输出功率控制仿真模型,并给出了电路仿真波形。结果表明,系统采用自适应模糊PID控制方法,能够应用模糊控制技术对PID参数进行在线修改,以满足不同时刻的功率偏差和偏差变化率对PID参数自整定的要求,使被控对象具有良好的动、静态性能,实现逆变电路的恒功率输出控制。
For the series resonant full bridge inverter circuit,The system adopts the controlling technology of self-adaptive fuzzy PID,establishes a simulation model of the system self-adaptive fuzzy PID output power control technology by using MATLAB,and gives the circuit simulation waveform.The results show that when adopting self-adaptive fuzzy PID method,the system can make online modifying by using fuzzy control technology to meet the requirements of PID parameters self-tuning according to the power error and error change rate at different time.At the same time,the controlled object has a good dynamic,static performance,to realize the constant power output control in inverter circuit.
