摘要
本文首先讨论参数优化方法在单变量系统参数整定中的应用,接着又将这种方法推广应用于单元机组协调控制系统的参数整定。文中,用单纯形优化算法,分别对一些典型的协调控制方案进行参数整定。结果表明,用参数优化方法解决单元机组协调控制系统参数整定问题是可行的;为使系统具有较好的动态品质,单元机组协调控制系统中各参数应该相互配合,但这种配合并不是唯一的;此外,结构复杂的协调控制系统,其控制性能并没有得到多大改善,因此,应该采用结构简单的控制方案。
The application of the optimization method to tuning SISO systems and, further, tuning coordinated control systems of Boiler-Turbine-Generator Units (BTGU) is discussed. A simplex optimization method is used to find tuning values of some typical BTGU coordinated control systems. Simulation results show that the application of the optimization method to tuning the controller of BTGU coordinated control system is feasihle; the parameters of the controller must he matched with each other for a good dynamic performance, but they are not unique. In addition, it also shows that a more complicated coordinated control system of BTGU does not improve its more performance. So, a simplex coordinated control system is preferred.
