【摘要】：隨著工業(yè)革命的進行,人們對于物資需求的逐步提升,人類文明社會對于能源的需求在不斷擴張,同時環(huán)境保護也備受關注,在權(quán)衡經(jīng)濟工業(yè)等的發(fā)展和環(huán)境保護的情況下,安全、有效、清潔式無污染的能源是未來發(fā)展不可或缺的。質(zhì)子交換膜燃料電池(PEMFC)作為一種新型清潔能源,對其的研究一直在進行,而對于PEMFC的控制方法研究也至關重要。對于這種具有高度非線性和不確定性的系統(tǒng),若能將控制問題轉(zhuǎn)換為抗擾問題,則控制起來會更加有效。本研究課題的內(nèi)容如下所示：1.根據(jù)質(zhì)子交換膜燃料電池的電功率動態(tài)模型和溫度動態(tài)模型對PEMFC的工作原理和電池特性進行分析,尤其對于PEMFC的溫度特性,通過對電堆溫度控制會造成影響的幾個因素分析對于電池溫度特性的影響。2.對經(jīng)典自抗擾控制技術進行了分析,由于經(jīng)典自抗擾控制技術中的非線性反饋組合部分具有一定的局限性,對于控制器的應用范圍和抗擾能力有一定限制�？紤]到這方面,在復合控制的思想上,將滑�？刂浦械那袚Q律的概念引入到自抗擾控制器中,提出了滑模自抗擾復合控制技術,并通過一個不確定二階系統(tǒng)的實例仿真對控制器的有效性和魯棒性進行驗證。3.質(zhì)子交換膜燃料電池(PEMFC)是本課題研究的對象,在對PEMFC系統(tǒng)進行擴張狀態(tài)的重構(gòu)后,將控制問題轉(zhuǎn)換為抗擾問題。針對PEMFC系統(tǒng)進行滑模自抗擾復合控制器的設計,對PEMFC溫度進行控制。在控制過程中,為驗證所提出的控制器的抗擾能力,進行了外部擾動、內(nèi)部不確定性、系統(tǒng)噪聲等的測試。同時,為驗證本課題提出的控制器具有更強的抗擾能力,具有相同參數(shù)的經(jīng)典自抗擾控制器也用于對PEMFC的控制。本課題的研究為這類具有不確定性和未知擾動的控制過程提供了一個新的控制策略研究方向。
[Abstract]:With the development of the industrial revolution and the gradual improvement of the material demand, the demand for energy is expanding continuously in the human civilization society, and the environmental protection is also being paid close attention to. Under the condition of weighing the development of economy, industry, and environmental protection, Safe, efficient and clean energy is indispensable for future development. As a new clean energy, proton exchange membrane fuel cell (PEMFC) has been studied all the time, and it is also very important to study the control method of PEMFC. For such a system with high nonlinearity and uncertainty, if the control problem can be transformed into a disturbance rejection problem, the control will be more effective. The contents of this research are as follows: 1. According to the dynamic model of electric power and temperature of proton exchange membrane fuel cell (PEMFC), the working principle and characteristics of PEMFC are analyzed, especially the temperature characteristic of PEMFC. The influence of several factors on the temperature characteristics of the battery is analyzed by means of several factors that will affect the temperature control of the stack. The classical ADRC technique is analyzed. Because of the limitation of the nonlinear feedback combination part in the classical ADRC control technique, the application scope and the immunity ability of the controller are limited to a certain extent. Considering this aspect, the concept of switching law in sliding mode control is introduced into the active disturbance rejection controller, and the sliding mode active disturbance rejection compound control technique is proposed. The effectiveness and robustness of the controller are verified by an example of an uncertain second order system. Proton exchange membrane fuel cell (PEMFC) is the object of this paper. After reconstructing the PEMFC system, the control problem is transformed into the disturbance rejection problem. The sliding mode active disturbance rejection controller is designed for PEMFC system and the temperature of PEMFC is controlled. In order to verify the robustness of the proposed controller, external disturbances, internal uncertainties and system noise are tested in the control process. At the same time, to verify that the proposed controller has stronger immunity, the classical ADRC with the same parameters is also used to control the PEMFC. The research in this paper provides a new control strategy research direction for this kind of control process with uncertainty and unknown disturbance.
