| 摘 要： | 在斩波式串级调速系统、永磁同步发电机变速风力发电系统和永磁直流无刷电机调速系统中需用直流升压斩波和降压斩波,它们的电流内环采用现有的电流调节器或电流跟踪控制方法都不合适.本文介绍一种新的电流峰值两点式控制(NPCTC),它能满足上述斩波控制要求,其特点是:不受非线性影响,电流响应快;开关频率固定,在电流断续时也能工作;一个开关周期中实际电流的平均值等于其设定值;在全部转速范围内都能稳定工作,且控制准确.

| Abstract: | The DC boost chopper and buck chopper are used in cascade drive systems with chopper, variable-speed wind turbines with permanent magnet generators and permanent magnet brushless DC motor drive systems. However, they are unsuitable to adopt usual current regulators and tracking current control method in their current feedback loop. A new peak current two-point control method (NPCTC) is proposed. It has the following advantages: fast current response unaffected by nonlinear, fixed switching frequency, able to work with discontinuous current, and stable working and accurate control in full speed range. Finally, simulation and experimental results verify the feasibility of the proposed guidelines. |
