中文摘要 | 本文提出一種方法可找出含可調參數非線性控制系統之有關漸近穩定 性與極限環之增益邊際和相位邊際。首先使用描述函數法將非線性控制系統線性 化,然後加入增益一相位邊際測試器,並將特性方程式分解成兩個穩定方程式, 最後應用參數平面法找出常數增益邊際和相位邊際之邊界。依據這些邊界,即可 獲得可調參數增益邊際和相位邊際之影響效應的有用資訊。含有一個傳輸延遲的 非線性俯仰定向飛行控制系統被用來說明本法之實用性。 |
英文摘要 | A method for finding the gain margins and phase margins of nonlinear control systems withadjustable parameters for asymptotic stability and for having limit cycles is presented. The consideredsystems are first linearized by the describing function method and modified by adding a gain-phasemargin tester, then the characteristic equations are formulated and factored into stability equations, andfinally the parameter-plane method is used to find the boundaries of constant gain margin and phasemargin. From these boundaries useful information about the effects of adjustable parameters on gainmargin and phase margins can be obtained. A pitch orientational nonlinear aircraft control system witha transport lag is used to illustrate the usefulness of the proposed method. |
