介绍了一种优化的比例积分微分（PID）控制器的实现方法，该控制器控制单相逆变器和单端初级电感DC/DC变换器（SEPIC）。主要的改进是赋予经典PID控制器梯度下降优化方法，它产生精确的值的PID控制器参数Kp，Ki和Kd，这反过来跟踪最大功率。该方法采用Ziegler-Nichols法后处理，缩短了优化时间。SEPIC最大功率点跟踪器（MPPT）可确保光伏电池的最佳利用率。该方法进一步证明了其在变负载条件下的有效性。采用TMS 320 F28335 DSP实现了可控脉宽调制（PWM）。控制系统已通过仿真验证，并在一个原型中实现。然后，实验结果与传统的单相逆变器进行了比较。
Introduced here is an implementation of an optimized Proportional, Integral, and Derivative (PID) controller that controls single-phase inverter and single-ended primary-inductor DC/DC converter (SEPIC). The main improvement is the endowment of classical PID controller with gradient-descent optimization method, which generates exact values for PID-controller parameters Kp, Ki, and Kd, which in turns track the maximum power. The method was applied post-use of Ziegler-Nichols method, reducing optimization time. SEPIC maximum-power-point tracker (MPPT) ensures optimal utilization of PV cells. The method further proves its efficacy in variable-load conditions. TMS320F28335 DSP has been used to implement the controlled pulse width modulation (PWM). The controlled system has been verified by simulation and implemented in a prototype. Then, experimental results have been compared with those for conventional single-phase inverter.
