Firstly, through analyzing massive materials and data, this paper summarizes the main problems of resources and environment confronted with jiangsu province, which are the decrease of per capita amount of land and water resources, the insufficient amount and low self - support rate of mineral and power resources, the low use efficiency and serious waste phenomena, the great emitting quantity of waste water, waste gas and kinds of pollutants, the worrying water quality of surface water and seawater, the bad air condition and the heavy pollution of acid rain
本文首先通過對大量的資料和數據分析，歸納了江蘇省資源、環境面臨的主要問題:土地、水資源人均佔有量持續遞減，礦產、能源資源總量少、自給率低，且各種資源存在利用效率不高、浪費嚴重等諸多問題;廢水、廢氣及污染物排放量大，地表水、海水水質堪憂，空氣質量差，酸雨污染較重。Abstract : iterative learning control is an effective approach to the control of processes that are repetitive in nature. in this paper, an open - closed - loop pi - type iterative learning control scheme for the precise tracking control of a class of discrete nonlinear time - varying systems over a finite time interval is presented. the scheme updates control input with tracking errors of both current and last iterations simultaneously. sufficient and necessary conditions which guarantee the convergence of the scheme are given and then proved with inductive method. finally, the conditions are verified with simulation results
文摘:對于具有重復運動性質的對象，迭代學習控制是一種有效的控制方法.針對一類離散非線性時變系統在有限時域上的精確軌跡跟蹤問題，提出了一種開閉環pi型迭代學習控制律.這種迭代律同時利用系統當前的跟蹤誤差和前次迭代控制的跟蹤誤差修正控製作用.給出了所提出的學習控制律收斂的充分必要條件，並採用歸納法進行了證明.最後用模擬結果對收斂條件進行了驗證
