  7. Abstract:
  8. Linear position sensors are widely used in linear motion-control systems. In this thesis, the design, optimization, performance analysis, and prototyping of a linear variable reluctance, variable air-gap length resolver are discussed. The accurate modelling of the studied sensor needs three-dimensional (3-D) time stepping finite element analysis (TSFEA) that is computationally expensive and unsuitable for co-usage with optimization algorithms. Therefore, the aim of this thesis is to establish an accurate, yet computationally fast, model suitable for optimal design of linear variable reluctance resolvers. The proposed mathematical model is presented based on modified winding function method. The proposed model is used for design optimization of the sensor. Then, 3D time-stepping finite-element method (3D TSFEM) is used to validate the design, optimization, and analytical model. The results of TSFEM show due to finite width of the core, there is end effect that affects the accuracy of the sensor. So, two methods are proposed to compensate the end effect of the sensor. Finally, a prototype of the sensor is built and tested. Comparison between the results of simulation and experimental tests verified the success of the proposed model
