| Summary: | 碩士 === 國立臺北科技大學 === 車輛工程系 === 106 === In Two-Mde Hybrid system, the Internal Combustion Engine (ICE) often shuts down and restarts to operate in its efficient zone while driving. As the mode shifts, the motor torque changes dramatically. These conditions could cause driveline vibrations.
A forward calculation model of Two-Mode Hybrid system with an ICE damper, Half-Shafts and tires is built up through MATLAB/Simulink to analyze driveline vibration caused by large torque output from power-sources. When larger torque is detected, Pulse Cancellation (PC) Control and Proportional-Integral-Derivative (PID) Control are applied. The Motor/Generators are controlled to provide feedback torques to eliminate the driveline vibration.
The result in frequency domain shows PC reduces 60% of vibration from ICE Damper while PID Control and PC-PID Combined Control provides over 75% of vibration reduction. PC-PID Control even provides traction force with nearly no vibrations.
