Deskripsi

For an internal combustion engine to attain greater fuel economy and performance per amount of emissions, variable valve-timing is often used. In this study, a PD controller for an electric driven planetary gear Variable Valve Timing (VVT) system is designed. The model under study consists of an electric motor integrated with a planetary gear system. The phase angle of the camshaft is controlled by VVT for the required torque and engine speed. A classical PD controller is designed using the root locus method, which is then benchmarked against a GA-optimized PD controller. Finally, a simulation study is carried out which demonstrates that GA-optimized controller has better performance and capability to maintain an optimum phase angle for maximum brake power and regulation of the fuel and air mixture.
