摘要:
在控制系统的设计过程中,通常需要加入调节器或控制器,才能使系统满足稳定性、准确性和快速性等性能指标。调节器或控制器的参数选择恰当与否对系统性能的影响非常大,因此,对控制系统调节器或控制器参数的优化设计十分重要。文中在给定控制器结构的前提下,不改变控制系统原设计,依靠系统的频率特性采用单纯形调优法,适当改变系统调节器或控制器的参数,使得实际的控制性能与期望的控制性能之间的差别最小化,就可以使优化后的控制系统的动态性能得到明显改善,具有优良的有效性和通用性。
Abstract:
In the process of designing an automatic control system,usually need to add some controllers or adjusters so that the control system can satisfy the performance index of stability,accuracy and rapidity. Whether the parameters of controllers or adjusters are appro-priate or not influences the performance of control system greatly,so it is very important to optimize these parameters. Under the premise of the given controller structure,without changing the original design of control system,relying on the frequency characteristics of the sys-tem use the simplex optimization method to change parameters of controller or adjusters,making the actual control performance with the desired control performance minimize the difference,which can make the optimized control system dynamic performance is significantly improved,with good validity and generality.
