具有期望性能的控制系统设计

CONTROL SYSTEM DESIGN WITH EXPECTED PERFORMANCES

本文给出的控制系统设计方案是在设计者已选定系统控制器结构的基础上,利用参数优化计算使所设计的控制系统具有期望的动静性能。它改进了现有控制系统设计方案大多数与系统的期望性能指标无直接关系的缺陷,避免了设计中为满足性能指标而进行的多次试凑。同时该方案在设计中还可包括系统的非线性特性。文中还给出了一种确定系统控制器结构的专家系统方案。最后的算例验证了该方案的实用性。

A new control system design scheme is proposed in this paper on the basis of given system controller structure. The scheme can make the designed control systems possess expected dynamic and static performances by using parameter optimization technique. It overcomes the demerit of most known control system design schemes which are not directly related to expected system performances, and avoids making trial and error many times to achieve expected performances. Moreover, the scheme allows system models to contain nonlinear characteristics. An expert system scheme for determining system controller structures is also provided . The given example demonstrates the practicality of the scheme.
