Abstract
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.
Highlights
Using ropeless elevator as transportation for a very high building which simple in construction and efficient in time-consuming has to face challenges that many researchers have to conduct more research and development in minimizing detent force
From Selvaperumal et al (2013) detent force rises because of changing the location of permanent magnet and sloth teeth in a synchronous motor which made vibration and noise appear on the systems
To support on previous research by (Lim and Krishnan, 2007) on Input curve graph is the result of first parameter display before experiencing Fuzzy-PID process
Summary
Using ropeless elevator as transportation for a very high building which simple in construction and efficient in time-consuming has to face challenges that many researchers have to conduct more research and development in minimizing detent force. Several ways used the most to deal with detent force such as by optimizing the structure design and dimension such as skewing which explained on research by Shin et al (2012), shorten space between slot by Shin et al (2017). It is only a few types of research that try to deal with detent force without transforming the structure which expensive and time consuming by using controllers. To overcome the problem (Lim and Krishnan, 2007) using permanent magnet switched reluctance motor and PI controller on the current has been already succeeded to reduce detent force by using particular load or distance
