As a kind of model predictive control, Generalized Predictive Control adopts prediction model, feedback correction and rolling optimization, etc, which has the characteristics of strong robustness and low model requirements, and can effectively overcome its shortcomings. In this paper, the mathematical model of air source heat pump is established, and the Generalized Predictive Control strategy is proposed. The Generalized Predictive Controller, PID controller and Fuzzy controller are designed on the MTALAB simulation platform.

Active vibration isolation technology has made rapid development in recent years. At present, it is in the stage of laboratory verification and trial application. In the early stage of the research, the theoretical research on control algorithm, control strategy and actuator has gradually turned to the integrated system research. Based on the active vibration isolation bench system, the design, development, detection and evaluation of the active vibration control system are completed by using the model development mode, and a set of simulation platform is built to verify and evaluate the design process. Active vibration isolation structure consists of signal pick-up system, excitation and monitoring system, actuator, power amplifier and passive vibration isolation platform, forming an integrated active vibration isolation platform, namely active control object. Based on the second-order active disturbance rejection control algorithm, the simulation model and experimental model of the control system are researched and developed, and the rapid development of the controller is realized by using the active disturbance rejection control technology. Based on the passive vibration isolation bench system and control system, the active vibration control experiment is completed, which verifies the correctness and effectiveness of the developed controller.

The unconsumed hydrogen coming from the stack usually contains a lot of nitrogen, and the effect of nitrogen mole fraction on the recirculation performance of the ejector needs to be studied. In this study, a two-dimensional Computational Fluid Dynamics model is developed to study the influence of nitrogen mole fraction in the secondary flow on the ejector’s performance. The results show that the recirculation performance of the ejector is sensitive to nitrogen mole fraction in the secondary flow, which is because of the influence of nitrogen on the fluid mixing inside the ejector. The recirculation ratio and nitrogen mole fraction show a linear positive correlation, while the hydrogen recirculation ratio shows a linear negative correlation. The minimum values of recirculation ratio and hydrogen recirculation ratio are 238 and 0.4 indicating that the recirculation performance of the ejector is acceptable.","PeriodicalId":107254,"journal":{"name":"2021 36th Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128931731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes an estimation method that combines extended Kalman filtering (EKF) and least squares method to identify the parameters of PMSM under the influence of magnetic saturation. This paper improves the PMSM model by establishing an inductance model considering magnetic saturation at first. Thereafter, EKF and least squares based method is proposed to estimate the magnetic flux and variation of inductances. The proposed method can accurately identify the machine parameters especially under the condition of magnetic saturation situation.
