Wind energy conversion system is a complicated field refers to electrical machine, power electronic, electrochemistry, material, mechanics, aerodynamics, computer, automation, aerography and etc. following the increasing demand of electric power and environmental protection all over the world, it is important to exploit the renewable and clean energy sources. this dissertation mainly aims at modeling and controlling each part of wecs and simulating the system response under different disturbances to develop a suitable controller
隨著電力需求的進一步增長，以及世界范圍內對環境保護、能源再生等問題的日益重視，二十一世紀將更加重視清潔能源和可再生能源的開發利用，我國現有的以煤電為主的電力結構也必將向發電類型多元化、能源再生化、能源「綠色」化轉變，因此，風力發電這種很有發展潛力的發電技術成為一個具有重大實際意義的課題。 -
The temperature of the washing water should under 40, and the hottest water should not over 60. if not it will age the washing barrel and the plastic. when finish working, the controller and the process should be restored
每次洗衣結束后，要排凈污水，用清水清洗洗衣機桶用干布擦乾洗衣機內外的水滴和積水將操作板上的各處旋鈕按鍵恢復原位排水開關指示在關閉位置，然後放置於乾燥通風處。 -
In order to decrease the over - adjusting in temperature and transaction time, a multi - model selector was provided to different scenarios of ascending temperature to make this system be simulated under simulink ' s circumstances. the result of simulation demonstrated that the effect of the system temperature control with model selector is superior to that of the system with pid controller or with pure lag compensation
為了進一步降低滲氮爐到溫前的溫度超調量及過渡時間，又提出用一個模式控制器來進行多種升溫方式的選擇並在simulink環境中對帶有模式控制器的溫控系統進行了模擬實現，模擬結果表明帶模式控制器的滲氮爐溫控系統的控溫效果又要優于帶純滯后補償的pid控制系統。
