The identification method utilizes genetic algorithm (GA) to identify fault parameters and unknown mode changes simultaneously based on global analytical redundancy relation (GARR). Fault parameters and mode change time of all switches are encoded into one chromosome as potential solution of the identification process. The GARR is adopted as the performance index of GA search. With the fault parameter values identified by the proposed method, we can tell the healthy status of monitored hybrid system. Experiment results show the efficiency of the proposed method.","PeriodicalId":188024,"journal":{"name":"2008 2nd International Symposium on Systems and Control in Aerospace and Astronautics","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114075925","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 meaning of leveling in the paper is to acquire two attitude angles of the roll and the pitch of the aircraft during its motion. The EKPF algorithm is applied to our inertial attitude reference unit based on the hemispherical resonator gyroscope (HRG), which is made in China. Simulation results indicate that the performance of the proposed leveling algorithm is superior to that of the standard extended Kalman filter (EKF).","PeriodicalId":188024,"journal":{"name":"2008 2nd International Symposium on Systems and Control in Aerospace and Astronautics","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116363353","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 whole aerodynamic model is unnecessary because there is no nonlinear direct state feedback base on the nominal aircraft model, and as a result, the sensitivity to aircraft model is decreased. The control structure is simple, re-allocation of control power and the reconfiguration of control law can be achieved conveniently and rapidly. The control law design and computer simulation for an aircraft with aerodynamic perturbation demonstrate that the robustness of the control law is increased.","PeriodicalId":188024,"journal":{"name":"2008 2nd International Symposium on Systems and Control in Aerospace and Astronautics","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126525163","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}

In this paper, we extend the concept of finite-time boundedness (FTB) for a class of linear discrete-time systems with time delay and time varying exogenous disturbances. Then, we present a new approach for finite-time control problems for these discrete-time systems. The main results provided are sufficient conditions for robust finite-time stabilization via state feedback. The conditions can be reduced to a feasibility problem involving linear matrix inequalities (LMIs).

The paper starts with an introduction of the basic concept of multi-satellite navigation system. It then follows a literature review covering mainly the current status of foreign and domestic research in this field. Subsequently, the key techniques of the GPS/GALILEO multi-satellite integrated navigation system have been explored, with the system of modeling method and control algorithm based on Kalman filtering technology as the research emphasis. Finally, the positioning errors of GPS, GALILEO and GPS/GALILEO systems are compared by the experiments along a typical route. Furthermore, the results show that the precision of navigation can be improved by way of multi-satellite integrated navigation because of more visible satellites and better space distribution structure. In particular, the modeling method and control algorithm for multi-satellite system presented in the paper will show the crucial significance in terms of improving accuracy in positioning applications.","PeriodicalId":188024,"journal":{"name":"2008 2nd International Symposium on Systems and Control in Aerospace and Astronautics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131394998","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 core component of the collision sensor is the MEMS accelerometers. The data acquisition, reduction, and crash determination are accomplished using a low cost PIC microcontroller. The crash condition is determined based on vehicle acceleration and variation of velocity. A backup Li-ion battery is incorporated into the system to prevent power shut down.

In this study, Jet element is investigated and the math model of jet element is constituted in order to decrease the switch time. The factors which effect the switch time are studied. The static and dynamic characteristics of the device were investigated analytically and by computer simulation. The results show that the math model of jet element is a third-order system, and the perimeters of system transfer function are different when jet element work in different conditions. The optimum value of area ratio between the supply channel and exhaust port for the factors which effect the switch time are different.
