For the convenience of imposing the amplitude constraints, generalized binary noise (GBN) is adopted as the excitation signal. Then based on the asymptotic principles of prediction error method (PEM), excitation signal spectral density and the upper bound of identified relative frequency-domain deviation are obtained via constructing and solving a set of linear matrix inequalities (LMIs). Owing to the statistical property of the obtained model, a probability constraint can be imposed to improve the model accuracy for robust control application. Simulation results demonstrate the advantage and effectiveness of the proposed approach.","PeriodicalId":421276,"journal":{"name":"2015 34th Chinese Control Conference (CCC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114893928","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}

According to the influence by the peak velocity, frequency, layout position, exit angles of synthetic jets and the angle of attack on lift, the optimal parameter combination was obtained. Based on the optimal parameter combination we provided a scheme that uses peak velocity of synthetic jet as the input. We also designed a synthetic jet controller for flight roll control at high angle of attack, which adopts the Robust LQR method to realize the stability control of roll (57.3 deg) at high angle of attack (18 deg). The simulation shows that the proposed control method has good control performance, and it overcomes the difficulty of using traditional aileron for flight roll control at high angle of attack.","PeriodicalId":421276,"journal":{"name":"2015 34th Chinese Control Conference (CCC)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115251935","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}

Precise control of piston motion is important for reliable operation of free piston engine. In this paper, a discrete-time control-oriented model of free piston system is derived based on the energy conservation equation. An optimal controller based on LQR technique is designed to control piston position. Concerning the impact of disturbance due to transient load requirement, the system is augmented with an integrator to stabilize the steady state error. Finally, effectiveness of the designed controller is tested in a high fidelity simulation model established in the AMESim environment and the results are satisfying.","PeriodicalId":421276,"journal":{"name":"2015 34th Chinese Control Conference (CCC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115494096","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}

The nonlinear model with vehicle dynamic behavior affected by such as tyre force, yaw rate and sideslip angle is firstly established. By using Dugoff tyre force model and the moving horizon optimal strategy, a programming problem of optimal desire slip ratio is furthermore presented in order to avoid understeer and oversteer. It is however difficult to compute on-line for the moving horizon optimal strategy. For this reason, an optimal desire slip ratio MAP according to off-line moving horizon optimal strategy is proposed. The simulation results show that the traction control performance is improved for the in-wheel motor electric vehicle while steering.","PeriodicalId":421276,"journal":{"name":"2015 34th Chinese Control Conference (CCC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122695476","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}
