基于DSP的单相逆变电源智能控制系统

针对逆变电源模糊控制系统输出存在振荡的问题，以数字信号处理器（DSP）为核心，将可变论域思想引入模糊自整定PID控制结构中，设计了一种基于可变论域的模糊自整定PI双闭环逆变电源控制器，实现了在线调整模糊论域的伸缩变化。仿真结果表明：阻性负载情况下，与常规PID控制器相比该控制器的输出超调小、自适应能力强，可以提高逆变电源系统的稳态精度和动态性能。

Single-phase inverter intelligent control system based on DSP

As a response to oscillation ~fecting output of inverter Fuzzy control system, this paper propo- ses a Fuzzy self-tuning PI double closed loop inverter controller based on variable universe, based on the digit- al signal processor （DSP） and by applying variable universe into Fuzzy self-tuning PID control structure, so as to achieve an online adaptive stretching changes of Fuzzy universe. The simulation results show that, in the case of resistive load, the controller, with a less output overshoot and a stronger adaptability than the conven- tional PID controller, is an improvement in the steady-state accuracy and dynamic performance.
