It adopts developed predictive model to shorten the predictive time and eliminate the truncation error, adopts range control to avoid the frequent change of inputs, adopts block technology to reduce the dimension of qp, uses performance ratio to make the controller ' s tuning sample and intuitionistic
該演算法中,作者採用改進的預測模型來減小模型時域與消除截斷誤差,形式上採用區間控制防止操縱變量的頻繁動作。並在演算法中實現了漏鬥技術與block技術,利用性能比來使得控制器調整簡單直觀。Thirdly, a modified extended chirp scaling ( ecs ) algorithm is presented, which solves the problem of producding fine focused images in the class of chirp scaling ( cs ) algorithm. lt can be used for uwb - sar imaging effectively. the phas e error produced by cs operation are analyzed. a windowed process in two dimension frequency domain before cs operation are proposed. it can improve the quality of image and widen the effectively swath and increase the peak to sidelobe ratio ( pslr )
然後針對chirpscaling ( cs )類演算法不能對參考點精確聚焦的問題,提出了一種改進的擴展cs ( ecs )演算法,實現了對uwb - sar的高效成像;分析了cs操作產生的相位誤差,提出在cs操作之前在二維頻率域對信號加窗,除有效提高信號的峰值旁瓣比( pslr )外,還可以提高圖像質量,增加有效測繪帶寬度。By use plc, system can complete function as follow : this auto - control system be applicable to the temperature and smoke and dust the deal the variety quick, control the process is difficult with the operation is ; by the temperature controlor can automatically follow to the wet tower " exit temperature, error in the ? 3 v including ; by to automatically spray fog to lower the electric resistance, with the function for full the electricity equipment accepting the dust ; because of adopting feedback closed loop, and come to a to respond to the speed quick, constant temprature control the accuracy is high ; because of adopting the sensors, and make the system circumstance to leak water quick ; system have many control parameter can set exit control temperature and adjust value low limit by key ; can communication with remote computer and have remote control
通過使用plc ,使該自控系統可以完成如下功能:適用於溫度及煙塵量變化快、控制過程難以操作的場合;通過溫控表自動跟蹤增濕塔出口溫度,誤差達到3以內;通過自動噴霧來降低粉塵比電阻,以此充分發揮電收塵器的作用;由於採取了閉環反饋迴路,達到了響應速度快,恆溫控制精度高;通過使用各種檢測傳感器,使得異常情況泄水快;該自控系統具有多套控制參數,增濕塔出口控制溫度及調節閥下限值可通過按鍵設定;可與上位機通訊,具有「現控遠控」功能。
