However, the development of solar power faces many difficulties, such as efficiency. The efficiency of the solar power generation system is determined by inverter, and the design of high frequency transformer is an important part in the inverter. In high-frequency fly-back transformer, leakage is a key parameter affecting energy consumption. In view of this situation, this paper analyzed methods of reducing leakage, and proposed a new method to calculate leakage through using the air gap, and then build a fly-back transformer model to verify this method.","PeriodicalId":386083,"journal":{"name":"2011 International Conference on Mechatronic Science, Electric Engineering and Computer (MEC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127204606","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 cooperative control architecture is composed with the steering controller and the braking controller. Based on the yaw moment and the front wheel angle controllers, the vehicle steering controller is designed to improve the respond and stability of the vehicle. On the same time, the anti-lock brake control system is designed. To reduce the difficulty in determining the compensation control law of commonly used cross the steering system and the braking system, a new cooperative error is defined firstly and a new cooperative error model of the vehicles is developed. Then a new practical cooperative control law based on the system stability and the optimal index is devised. It is quite feasible because of its analytical form. The brake force distribution policy applicable to the complex work condition is presented. Finally, the stability and the validity of the control algorithm is validated by simulation results.","PeriodicalId":386083,"journal":{"name":"2011 International Conference on Mechatronic Science, Electric Engineering and Computer (MEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127497260","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 new scheme utilized (t, n)-threshold to share the secret image and embedded the produced n shadows into different cover images, any t out of n shadows can reveal the original secret image, and the cover images could be reconstructed with limited distortion.

In the simulation of a Driver-Vehicle-Environment system, a driver model is essential to correct the steering wheel angle input in right time based on the road conditions. In this paper, a new driver model is introduced. Firstly, a real-time algorithm based on dynamic parameters of vehicle body is established to estimate body posture in the next moment. Secondly, body posture is compared with the target trajectory to acquire the deviation quantity. Then, a correction of angle at the steering wheel is obtained. In Matlab simulink also a model of steering system is built up in this paper, for the purpose to simulate the steering force in steering control, which can be further extended in power steering simulation and active steering. Finally, two typical road condition simulation results show that the model in Driver-Vehicle-Environment closed loop system is feasible and effective.","PeriodicalId":386083,"journal":{"name":"2011 International Conference on Mechatronic Science, Electric Engineering and Computer (MEC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130511123","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}
