| 摘 要： | 提出一种基于免疫算法的多变量控制系统PID参数优化方法。首先对免疫算法的步骤和实现过程进行了介绍;接着采用了一种新的、适合多变量系统特点的控制系统性能指标,即用阶跃响应曲线超出期望变化区域的面积的大小来衡量控制系统的优劣。该指标被用于构造免疫算法的适应度函数。论文最后将上述方法用于火电机组负荷控制系统优化,取得了良好的效果。

| Abstract: | This paper proposes a new optimization method of the PID parameters in multivariable control systems based on immune algorithm. The way to implement its steps is described. A new appropriate performance index is used to form a proper function in the immune algorithm and the index can evaluate the performance of the multivariable Control systems by the areas exceeding a specified time -domain bounds. This-method has been applied to a load control system in a power plant. The simulating result has proved very effectiveness. |
