In this paper, the calibration work of a planar parallel manipulator was presented in details. And an innovative algorithm to solve the nonlinear optimization problem was proposed, which's named “Random-Levenberg-Marquardt” algorithm. With specific illustration and practical experiment result, this algorithm was proved to be efficient, accurate and easily implementable comparing to the traditional methods.","PeriodicalId":211049,"journal":{"name":"2011 9th World Congress on Intelligent Control and Automation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131778644","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 adaptive fault tolerant control scheme is designed via two (PID) Proportional -Integral - derivative controllers and a nonlinear observer. The nonlinear model of two inverted robot joints arms on a cart and has been studied and simulated with presence of an additive fault and a disturbance (white noise) in the system. The nonlinear adaptive observer is designed to eliminate the effect of the Coriolis and centrifugal torque and detect the fault and noise. The two PID controllers compensate the errors to increase the integrity of the strategy. The proposed strategy reconfigures the control law to overcome the errors and faults. An illustrated example is simulated and the encouraged results have been obtained.","PeriodicalId":211049,"journal":{"name":"2011 9th World Congress on Intelligent Control and Automation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130677288","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 Central pattern generator (CPG) network and a knee-to-hip mapping function are presented to realize the rhythmic motion for the quadruped robot. Based on genetic algorithm (GA), basic animal-like gait patterns can be realized. Moreover, the animal's vestibular reflex mechanism is mimicked to realize the adaptive walking of the quadruped robot on slope terrain. Entrainment with the sensory feedback from robot-environment interaction, the robot can walk up and down a slope smoothly. The presented CPG-based control method is validated through simulations and experiments with AIBO. Under the control of the presented CPG network, AIBO can realize animal-like walking pattern. Couples with the body attitude feedback signals, it also can cope with slipping, falling down and walk on a slope successfully, which demonstrate the effectiveness of the proposed biological inspired control method.","PeriodicalId":211049,"journal":{"name":"2011 9th World Congress on Intelligent Control and Automation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130712389","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 fuzzy planner processes data from infrared sensors to get the navigation angle in which the robot should be necessarily driven to avoid obstacles. The navigation angle acts as the input value of the speed arithmetic unit, which will generate the given speed values for the motion controls of the left and right driving wheels according to the kinematics model.

Some strategies are used for the implementation of on line path planning. One hand the population size equals to the sum of the number of the range sensors and the goal's number and the initial population values are decided by the informations of the sensors and goal too. On the other hand a virtual local environment based on current range sensors data is build in order to further shorten the searching solution time.
