This dissertation is about controlling and synchronizing multi PMSM using the proposed technique, namely hybrid cross coupling - master slave (CC-MS) technique. The application of this control and synchronization is for electric multiple unit (EMU) electric trains. In controlling the electric train, there are several things that need to be considered, including the speed of each wheel is the same when the road is straight or turning and the wheel slip occurs on the motorized wheel. In the initial stage, a PMSM simulation with ladder function is carried out. In the multi PMSM simulation, the parameterization of the selected motor needs to be done so that the mathematical equations of the PMSM can be simulated in the Matab-Simulink environment. In the next stage is a multi PMSM simulation with an electric train, so the mathematical model of the electric train needs to be derived. Building a train model begins with selecting the type of train by taking into account the mass of the train, type of motor, motor power, carriage configuration for calculating the counter-acceleration force, and the counter-air force. The design of a test bed in the form of a roller rig has been carried out for train applications. The design includes a train inertial simulator and a counter air force simulator. The selected roller is single roller, multi axle and vertical type. The selection of this type is based on considerations of ease of design but is capable of being a wheel and rail interaction simulator for wheel anti-slip design. In building the anti-slip adhesion of the roller rig it is necessary to initialize it for dry, watery and oily conditions. The results of the initialization of the adhesion can calculate the torque limiter as an anti-slip wheel. there is steady state error when synchronization work together with anti-slip before re-tunning process. Synchronization and anti-slip are running well after re-tunning (with contaminant in steady state or step function)
