基于改进双抛物线的电流跟踪技术控制算法
Current Tracking Control Technology Based on Improved Dual Parabola Algorithm
摘要
Abstract
In order to overcome the difficulties in realizing the parabola benchmark current loop and the breaking point inaccuracy,we proposed an improved parabolic current control algorithm based on the current control pulse width modulation(PWM) converter model.Moreover,we compared three methods of dual parabolic current control and the improved algorithm with accurate breaking point through calculation of the formulas and simulation.The results show that the Newton-dual parabolic current control technique is more precise than oblique line-dual parabolic current control and PWM signal cycle is constant basically;And the technique makes the comparison circuit simplifier and increases the distance of the breaking point.The control process is easier to implement compared with the general double parabolic current control.Research results show that the improved Newton double parabolic control technology is a combination the advantages of dual parabolic current control and oblique line-dual parabola current control,which is feasible and superior.关键词
