In this paper, 2-D finite element analysis and MATLAB/Simulink software are used to model and simulate the proposed tubular linear switched reluctance actuator. The analysis of the actuator by finite element is essential for determining the magnetization characteristics. The obtained data from the analysis is useful for testing and verifying the machine operation performance and behavior. According to the analysis, when a step current signal of 3A was applied to the actuator, oscillation occurred at beginning of the motion with maximum overshooting of 2mm and settling time of 0.15s. Besides, the force analysis showed there was nonlinear force behavior between - 3.5N and 2N observed from the actuator motion. The saturation and nonlinear magnetization curve of materials causes the nonlinearity characteristics of thrust force and magnetic flux which affect the performance of the actuator. The determination of the characteristics and performance is crucial for the proposed actuator to realize a precision positioning system in the future.
