Title Proper : QUANTITATIVE MEASURE OF REGULAR LANGUAGES FOR SUPERVISORY CONTROL OF ENGINEERING APPLICATIONS
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : This dissertation formulates a signed real measure of sublanguages of regular languagesbased on the principle of automata theory and real analysis. The measureallows total ordering of any set of partially ordered sublanguages of a regular languagefor quantitative evaluation of the controlled behavior of deterministic .nitestate automata (DFSA) under di.erent supervisors. The computational complexityof the language measure algorithm is polynomial in the number of DFSA states.An online parameter identi.cation procedure is presented for computation of thelanguage measure parameters.A discrete event behavior-based multi-robot system has been designed andconstructed to validate the language measure theory and its applications to supervisorycontrol in the discrete-event setting. Each robot is equipped with multiplesensors and multiple actuators. The interactions between the robot(s) and the(possibly) dynamically changing environment are characterized by discrete-eventand continuous models, and the design and analysis of the robotic system are presentedin both continuous-time and discrete event domains. The robustness andreliability of the controlled behavior is guaranteed in the continuous-time domain.For example, visual servoing is applied to robot navigation during اapproachingtargetب and the vector .eld historgam (VFH) method is used for robust اobstacleavoidance.ب The discrete event interactions between behaviors are formulated as asupervisory control theory problem, where multiple supervisors are synthesized andimplemented online for robot control under di.erent speci.cations.
