Permanent magnet synchronous motor as an actuator for ropeless elevator has several challenges that have to reduce to make the system stable and secure. Detent force as one of a problem for having stabilization system is going to investigate on how its performance under fuzzy logic controller with a nonlinear test such as variations on load and distance to get a policy that can be used for industrial field or other human activities. Preliminary research is presented in this study by making a simulation of control with a fuzzy logic application by Mamdani design and this also aims to compare the previous PI simulation paper. In this fuzzy controller, simulation made with parameters which can cause the existence of detent force such as load, speed, distance, current and power to analyze how the performance under variation situation. With this simulation yield that fuzzy can relatively minimize detent force without considering the impact of saturation or hysteresis on the controller. The simulation is done on 2018 in electrical department of Universitas Indonesia by using the MATLAB R2010a toolbox.
