Fault diagnosis observer is established, where the Lyapunov stability theory is used to obtain the required adaptive tuning rules for the estimation of the nonlinear actuator faults.

Considering the whole system, positive displacement cross feedback and negative velocity cross feedback are adopted to provide precession damping and nutation damping for the rotor, furthermore the cross feedback controller is designed by root locus method, eigenvalues are guaranteed in the left-half plane of the root locus map, and gyroscopic effects of the rotor are restrained; the notch compensator based on coordinate transform is adopted to compensate the synchronous component in the displacements of the rotor, and the synchronous vibration is restrained. The parameters of cross feedback controller are designed from the root locus simulation, and the control methods are validated on dSPACE digital control environment. Experimental results show that the controller based on the framework of cross feedback control and notch compensator leads to a good system performance, and the control power is prominently reduced.","PeriodicalId":210380,"journal":{"name":"Proceedings of 2011 International Conference on Modelling, Identification and Control","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121286859","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 main idea is to acquire the position and orientation information of the platform by the coordinate measuring machine and construct a residual equation with uniform units. Then the platform's geometry parameters can be identified to compensate for its kinematics errors. The advantages of this method are that each geometry parameter's identifiability is ensured; no special auxiliary calibration equipments or redundant sensors are required to be designed and manufactured high adaptability and good operating characteristic are available. After the calibration procedure is described and the strategy on constructing the residual equation is discussed, a simulation shows that the kinematics accuracy after calibration can reach the same order of magnitude as measurement noises. Applying this method to an actual Stewart platform, the accuracy improves more than 5 times after compensation.","PeriodicalId":210380,"journal":{"name":"Proceedings of 2011 International Conference on Modelling, Identification and Control","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122551268","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}

However, on-line calculation for thermal efficiency of boiler still have difficulties, which the coal quality are often changing and not well obtained real-time. This paper identify the heating value of the coal into the boiler, aiming at the on-line calculation of the boiler efficiency, by means of the dynamic mass and energy balance method. Then an on-line calculation model for thermal efficiency of the boiler was established based on the indirect heat balance method. The paper illustrates the effectiveness of the models as well as the validation of the on-line simulation, starting from real operation data. The outcome is that it is possible to significantly satisfy the accuracy of on-line identification of the Low Heating Value (LHV) of the coal into the boiler, and the real-time of on-line calculations provided by indirect heat balance method.
