Research of Dynamic Voltage Restorer base on the Model-free adaptive control

摘要

A new control method, a model-free adaptive control,is used to resolve the steady-state error, insensitivity to the disturbance of power system, adaptive load is bad which is existed in feedforward control method of traditional, it only use the the data of load voltage and input voltage to determine the controller parameters, no need to establish the mathematical model of the system, Only by adjusting the parameters of a line, to achieve interference suppression system, the purpose of load voltage stability base on the theory analysis made emulation research and made the compare with the traditional feedforward control method . The Simulation results make clear that the correctness and feasibility of the method.
