| Summary: | 碩士 === 華梵大學 === 機電工程研究所 === 94 === A mass rapid transit (MRT) vehicle usually consists of eleven subsystems to perform functions in each aspect as to achieve demanded performance for its successful operation, and it is also realized the driving subsystem is the most vital equipment of an effective accomplishment during the running processes. Within this research, vector-oriented control approach was first adopted in establishing a simple mathematical model, which characterized the induction motors used in the mass rapid transit vehicle, and a utility, POWER SYSTEM BLOCKSET, of a well-known commercial code MATLAB/SIMULINK was employed to design the driver model for the induction motors and to simulate the MRT vehicle’s overall operations from starting, accelerating, sliding, up to desecrating and stop.
Furthermore, basic control theories such PI and Fuzzy control approaches were explored in examining the control performances of a MRT vehicle on the test track and in comparisons with the experimental data. It was verified that the fuzzy controller developed in this thesis can certainly fulfill the operating necessities of the MRT vehicles, which are even though conducted using the conventional PI controlling method. Consequently, the fuzzy control approach for maneuvering MRT vehicles is a prospective candidate with more flexibility in the near future.
