- In this thesis, the actual train of Taipei Rapid Transit Systems (TRTS) is modeled with MATLAB/ Simulink. It consists of three main parts which are traction system, third rail voltage and load. The traction system consists of induction motor with variable voltage variable frequency (VVVF) control, switching modes (SPWM, Quasi Six-step, and Sis Step), and three phase bridge inverter. The load consists of starting resistance, the running resistance during train movement, and gradient and curve resistances from the track profile. Four operation modes are used in the speed regulation which are acceleration, cruising, coasting, and braking. Single Input Fuzzy Logic Controller (SIFLC) proposed to replace the use of Fuzzy Logic Controller (FLC). It has the same performance as FLC. However, SIFLC offers significant reduction in the rule base, it makes the tuning easier. Since SIFLC uses Sliding Mode Control (SMC) concept, its stability can be proved. A case study with different treatment is presented to prove that the controller can work well regardless the gradient changes or load variations. In this case, the acceleration and jerk are limited within ± 1 m/s 2 and ± 1 m/s 3 , respectively. The results show that the speed can follow the reference well regardless gradient and load variations. Regenerative braking and coasting mode are successfully implemented. In the case of no-load, regenerative braking produces energy up to 48 % from the total energy consumption while in full-load it can produces up to 51 %.
