Derived control algorithms for speed and position control are based on forced dynamics principles and achieve prescribed speed and position responses. Inner speed control loop complies with principles of vector control. Outer position control algorithm respects damping factor of flexible coupling and achieves control of the load position with prescribed closed loop dynamics. Position control system with the measurements of motor current and load position only is completed with the set of observers, which generate all the state variables necessary for control including torques acting on the motor and load side.

In order to accelerate this process, a finite element model is developed. The model takes the nonlinear electrical and thermal coupled material properties into account. Furthermore it is able to calculate the electric and thermal behavior of a painted or taped stress grading system. The goal of this work is to present strategies to determine optimal stress grading-configurations for a minimization of the electrical as well as the combined electrical-thermal stress caused by the potential grading. Therefore, several numerical, global bounded optimization algorithms are implemented in the finite-element-model and analyzed regarding efficiency and effectiveness. As a result a self developed partial swarm based simplex optimization algorithm (PSBSO), is introduced which obtains the best result for this special optimization problem. This hybrid-algorithm combines the positive features of particle swarm optimization (PSO) and globalized bounded nelder-mead algorithm (GBNM).","PeriodicalId":382406,"journal":{"name":"2012 13th International Conference on Optimization of Electrical and Electronic Equipment (OPTIM)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129858532","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 motor offers the promise of eliminating a number of design limitations of existing electromechanical actuator systems. First, the motor eliminates the need for a gear set. This reduces the complexity of the package, which could result in a less expensive, more reliable, lighter and smaller overall package. Second, the harmonic motor inherently provides zero-force back-drivability and fails silent, greatly expanding the design space and simplifies the system fault analysis. Third, the motor has a low rotational inertia that could be used to improve the dynamic response of the system, improving both stopping distances and anti-lock braking control-ability. This work discusses a preliminary structure intended to show that the performance characteristics can be met and in particular that a specified torque can be obtained within given dimensional constraints. Simple analytical calculations based on magnetic circuits are first used to initiate linear and nonlinear finite element calculations of fields of forces.","PeriodicalId":382406,"journal":{"name":"2012 13th International Conference on Optimization of Electrical and Electronic Equipment (OPTIM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129001314","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}
