Modeling and Simulation of Series Parallel Hybrid Electrical Vehicle (SPHEV)

The project was about modeling and simulation of Series Parallel Hybrid Electrical
Vehicle using the MATLAB/Simulink as the based software. Based on the vehicle's
real specification and right components sizing, a SPHEV Simulink model was
developed and simulated to observe and study the operations of SPHEV under various
driving conditions. The model developed was a forward looking model utilizing the
driver model controller to request for power demand. The controller would execute
the power demand and choose which mode to be used. Since the SPHEV was a
combination of series and parallel modes, a good control strategy was required to
ensure the vehicle was operating at the right mode depends on the driving situation.
The simulation of SPHEV model was based on Urban Dynamometer Driving
Schedule (UDDS) reference drive cycle and it was successfully simulated.
xPC Target as a powerful tool is used to rapidly implementing real time control
system on a DC Motor. The xPC Target control system consist of three major
components which are Host PC, Target PC and hardware. The motor is used as
hardware of xPC Target as well as to represent the SPHEV system. The motor
controller which has been designed in Host PC is compiled and downloaded to the
Target PC which is running in real time operating system. The operating system will
execute the controller and control the hardware. Variation of motor's load which also
corresponds to variations of driving range in the SPHEV system will contribute to
different speed of motor. The acquired speed is used by the controller to compensate
with errors occur during the implementation.
