PID控制器参数主要是人工调整，这种方法不仅费时，而且不能保证获得最佳的性能。PSO已经广泛应用于函数优化、神经网络训练、模式分类、模糊系统控制以及其它应用领域，本案例将使用PSO进行PID控制器参数的优化设计。-The main parameters of PID controller are manual adjustment. This method is not only time-consuming, but also can not guarantee the best performance. PSO has been widely used in function optimization, neural network training, pattern classification, fuzzy system control and other applications, this case will be used to optimize the parameters of the PID controller PSO.
