摘要
异步电机作为目前国内应用广泛的电机,由于效率限制而在实际工况中存在很严重的能源浪费现象。黄金分割法应用于异步电机效率优化控制是一种较有效的方法,但存在鲁棒性较差、搜索区间大、响应速度慢等缺点,因此提出一种改进黄金分割法效率优化策略,以提高系统的响应速度、性能稳定。使用MATLAB软件对系统进行建模仿真,验证了提出的控制策略的优势。
Asynchronous motors are currently the most widely used motors in China.Due to efficiency limitations,there is a serious waste of energy in actual working conditions.Applying the golden section method to the efficiency optimization control strategy is a good method,but it has the disadvantages of poor robustness,large search interval and slow response speed.Therefore,an optimization strategy for improving the efficiency of the golden section method is proposed to improve the response speed and stable performance of the system.MATLAB software is used to model and simulate the system,and the advantages of the proposed control strategy are verified.
