Abstract

The use of hybrid energy systems has gone wide in the transportation industry, and especially with electrical vehicle, which has caused a lot of studies and researches to be conducted on this area. This system requires an appropriate controller design to maintain the variation of the voltages and currents in an electrical system that affect the overall output of the system, which results in an overall controlled performance of the vehicle. This makes controlling theses variables an essential need in order to obtain an efficient and high quality system, because vehicles can accelerate and decelerate instantly and they require instant high power supply sources. This demand of high power cannot be provided by a single power source, therefore, an auxiliary power source to overcome the high and instantons demand of power is required. The proposed control method in this research is called Generic Model control (GMC), which is a nonlinear control method that is widely used in the industry to control nonlinear systems. GMC maintains the output of the process variables at a desired rate in a process by manipulating certain effective variables.

The project discusses the proposal design of two dc-dc converters to boost and buck voltages as required by the load to ensure a stable closed-loop energy supply system. The main electronic components that are required in order to design a HESS in Electric Vehicle (EV) will also be explained and discussed separately in details along with their functionality and effects on the vehicle. This research also discusses the modelling of the overall systems and implementing the derived binary equations into GMC and implement the overall closed loop control system into Simulink. The tuning methodology of GMC parameters K1 and K2 is also discussed in this report. The results of this simulation is illustrated in graphs that show the behaviour of the voltages and currents of different components in the system and the effectiveness of the control system on the performance of the vehicle.
