The setpoint alarms can be configured to suit a variety of control and alarm requirements 通過設(shè)定定位點警報能滿足各種控制和警報的要求。
When the altitude control senses a drop in level below the predetermined setpoint the valve opens to fill tank 當(dāng)水位控制器感應(yīng)到水位下降到預(yù)置設(shè)置點以下時,則閥門開啟,開始對容器注水。
Mpc was successfully applied to the spacecraft rate control ( setpoint and tracking problems ) when applied on an internally stabilized model of the plant dynamics 在控制對象內(nèi)部嵌入穩(wěn)定模型, mpc法可成功地應(yīng)用于飛行器的速度控制。
Control algorithm is neural network self - learning , it means that measurement signals are inputed for neural network which adjusts the setpoint of actuators based on its efficiency , in order to improve strip flatness 控制算法為神經(jīng)元網(wǎng)絡(luò)自學(xué)習(xí)的算法,即輸入實測信號根據(jù)效率逐一調(diào)節(jié)執(zhí)行元件的設(shè)定值,以改善板形。
This control structure allows for separate controllers to be designed to handle setpoint changes and load disturbances . another desirable feature is that it allows for simple closed - loop determination of the process model 這種控制結(jié)構(gòu)允許對處理設(shè)定值改變和負(fù)載擾動分別進行設(shè)計,另一個特點是這種控制器考慮了過程模型的單閉環(huán)性質(zhì)。
Under the perfect model assumption , the characteristic equations for the setpoint change and load disturbance are distinct and include the process model and the controller designed to handle each disturbance 在假定準(zhǔn)確的模型前提下, pec控制對設(shè)定值改變和存在干擾的特征方程式是獨特的,其中還包括了過程模型和控制器處理各種擾動的設(shè)計。
One is feed - forward - feedback method based on turbidity . another is expert system with self - studying mechanism . fore - back and feedback system based on nephelometer can control the quality of water produced in the little range by setpoint 基于濁度的前饋?反饋控制雖然在一定程度上解決了穩(wěn)定性與控制精度之間的矛盾,能將出廠水質(zhì)量控制在設(shè)置值附近。
It is a quasi - optimization of both the response to setpoint and the response to load disturbance changes simultaneously . the simulation shows that this method is effective to most of the process models : the resulting pid settings have good performance of disturbance attenuation and robustness , and the use of setpoint weighting make good improve to setpoint response 仿真結(jié)果表明,本文提出的算法對多數(shù)的工業(yè)對象都是有效的,系統(tǒng)性能優(yōu)良,而且具有較好的魯棒性和抗干擾性,利用權(quán)值也很好的改善了給定值的跟蹤響應(yīng)。
Abstract : the gpc or crhpc strategy with input constraints will be possible to lead to infeasibility of the control algorithm and the performance of the control system will get degradation or instable . in order to overcome this problem , a control algorithm with guaranteed feasibility is proposed in this paper . it is shown that the algorithm makes the plant asymptotically stable and drives condition setpoint close to the actual setpoint of the plant 文摘:在系統(tǒng)輸入受限的情況下,采用一般的廣義預(yù)測控制或受限時域預(yù)測控制有可能會造成控制算法不可行,從而使系統(tǒng)的性能變壞或不穩(wěn)定.針對這個問題,本文提出一種保證可行性的控制算法,并證明該算法能夠使系統(tǒng)漸近穩(wěn)定且最終使條件設(shè)定值跟蹤系統(tǒng)的實際設(shè)定值
