Research on guidance and adhesion control strategies for independently rotating wheels of trams
Independently rotating wheels (IRWs) suffer from inadequate performance in lateral restoration and curve guidance. This paper focuses on studying the guidance control strategies
taking the IRWs driven by traction motors as the research object. To resolve the problem that the PID parameters need to be reset following any change in the system parameters for lateral displacement control
a parameter self-adaptive adjustment strategy based on fuzzy logic control was proposed. In addition
recognizing that the realization of guidance torque depends on wheel-rail adhesion
this paper proposed a torque distribution strategy that takes into account adhesion restrictions and was based on optimized adhesion control. Finally
the proposed control strategies were verified using an electromechanical coupling simulation model built with MATLAB and Simpack. The results show that IRWs still behave with good guidance ability to adapt to the changes in the system parameters and deteriorating track conditions.
