Basically, the control variables to be determined are the amounts of jump in the continuous states such that a corresponding cost functional is minimized. Based on a variational approach, necessary conditions of optimality are first established. The problem is then cast as a parametric optimization problem where the gradient information is derived. Finally and under some assumptions, convergence to the optimal solution of a conceptual algorithm is established. A brief discussion on the main implementation issues is also included.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122154519","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 general gasoline engines, engine load is controlled by throttling. On the other hand, CVTL can control engine load by altering intake valve lift and valve opening period under all engine load and speed conditions. Hence, CVTL requires high-precision control of intake valve lift in order to realize small engine load change at low engine speed condition such as idle condition. However, the dynamics of CVTL indicates non-linear characteristics, for example mechanical friction, backlash and hysteresis, because CVTL is generally composed of some gears and multi-link mechanisms. Therefore, it is difficult to realize smooth and small micro step of valve lift. This difficulty worsens the stability of idle speed control and smoothness of drivability. Consequently, a sliding-mode controller using delta-sigma modulation instead of previous non-linear switching input was developed and introduced to the valve lift control of CVTL. The sliding-mode controller could significantly improve the precision and smoothness of valve lift control.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"272 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131610562","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}

A two degrees of freedom control structure is proposed to prevent vehicle skidding during critical maneuvers through the application of differential braking between right and left wheels in order to control yaw motion. The feed-forward filter is a reference generator which compute the desired yaw rate on the basis of the steering angle, while the feedback controller is designed to track the reference as close as possible and to satisfy suitable loop robustness requirements. Mixed-sensitivity minimization techniques are exploited in order to design the loop controller. The performance of the control system is evaluated through Hardware In-the-Loop Simulation (HILS) system both under emergency maneuvers and in noncritical driving conditions, i.e. when the VDC system is not supposed to intervene.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125293430","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 controller has an inner current control loop with a bank of passive resonators working in parallel that contribute with a high gain to track the desired current reference. The outer control loop takes care of the regulation of the mean value of the DC output voltage of the converter.

The objective is to design a scheme which is able to find the best value for the gain beta within a predetermined set in order to generate the real control input to the plant.

Then the demand to suppressing output voltage change becomes still severer. We proposed an aproximate 2DOF digital controller which realizes the start-up response and dynamic load response independently. The controller makes the control bandwidth wider, and at the same time makes a variation of the output voltage small at sudden changes of loads and the input voltages. In this paper, a new approximate 2DOF digital controller using additional zeros is proposed. The new controller makes a variation of the output voltage more small at sudden changes of loads and the input voltages. This controller is actually implemented on a DSP and is connected to a DC-DC converter. Experimental studies demonstrate that this type of digital controller can satisfy given severe specifications.","PeriodicalId":176828,"journal":{"name":"2007 IEEE International Conference on Control Applications","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116488850","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}

Multiple time delays are in the state, and the delayed terms are also found in the control input and interconnection. The time-varying parameter uncertainties are unknown and norm-bounded. Sufficient conditions for the existence of the guaranteed cost controllers are derived.
