Abstract:	若追蹤控制系統爲非線性，一般均將系統加以線性化以解決之，但有些控制系統中其非線性項對系統之控制功能影響很大，必須尋找一適當之控制策略加以控制。若採用線性控制策略，額外地增加系統對強健性的要求，因此採用非線性追蹤控制爲此解決之道。本文擬用高階多項式回授理論以解決之，依據最佳控制理論在求控制律時，首先將costate vector以高階多項式矩陣來表示，最後多項式回授之各次項係數矩陣解，則依最佳控制理論以求得之，作者曾使用二次項回授爲非線性追蹤控制系統之近似解，本文擬將控制律延伸至高次項，使控制律更能掌握及解決系統中非線性項對控制功能之影響。由於現代計算機之高速率及高記憶體使多項式回授控制作爲即時控制變爲可行。 For a nonlinear tracking control system, linearizing the nonlinear system and then a linear control algorithm is generally applied to design the control system. But for some nonlinear control system the effect of nonlinear term to control performance is tremendous, the linear control law cannot satisfy the control performance of the nonlinear system. In this paper we propose a nonlinear control law to solve the nonlinear problem. In this paper we will use the higher order polynomial feedback control law to control the nonlinear tracking system. According the optimal control theory, the costate vector is firstly expressed as higher order polynomial matrix and then the matrix coefficient of high order polynomial feedback control law is finally solved.
