SPHEV Design using PI/PD/PID Controller

This paper deals with the increasing oil price and mounting environment concerns, cleaner and sustainable energy solutions have been demanded. At present transportation constitutes a large portion of the energy consumed and pollution created. One of the efficient solutions is the existence of vehicle that works on both fuel energy and electrical energy with optimized performance. HEV with different structures such as series, parallel, series parallel has been studied so far. HEV is consists of mainly two design elements mechanical and electrical. Mechanical design part includes ICE Car Dynamics while Electrical part includes Controller Design and Electrical Subsystem. This dissertation work especially focuses on the controller design of HEV. HEV control section includes four different rudiments to be controlled. These are engine speed controller generator controller motor controller and battery controller. In this work we have considered design of proportional integral (PI), proportional derivative (PD), proportional integral derivative (PID)for analysis of engine, motor and generator performance. This leads to the development of component models of the physical system such as the power distribution system and mechanical driveline. We also show the development of an energy management strategy for several modes of operation including the full electric hybrid and combustion engine modes. Finally we show how an integrated environment facilitates the combination of various subsystems and enables engineers to verify that overall performance meets the desired requirements. In this dissertation work design of electrical part i.e. control design and ESS design has been carried out. The designed SPHEV has been analyzed with the step change accelerator profile for the PI, PD, PID using performance measures such as rise time settling time peak time and peak overshoot.
