Incremental Conductance: In the incremental conductance algorithm, we find the derivative of PV output power with respect to output voltage. The dP/dV is evaluated and the algorithm keeps checking this value and changes the duty cycle such that dP/dV=- I/V = 0. This is the point at which maximum power is transferred. If dP/dV is greater than zero, it means the PV is operating to the left of the MPP. If dP/dV is less than zero, it means the PV is operating to the right of the MPP. This method holds an advantage over the perturb and observe method since it is fast and does not oscillate around MPP. However, the method could experience instability due the involvement of the derivative.

将模糊控制和普通PID相结合，自适应模糊PID控制效果明显优于普通PID控制，绝对正确，下载就能用(PID fuzzy control and the general combination of adaptive fuzzy PID control is better than normal PID control, absolutely right, you can use to download)
