Abstract

Various control intervention thresholds have been introduced to the automotive industries as it can reduce the possibility of road crash occurrences. This project’s aims are to derive transfer function of acceleration and braking of vehicle MATLAB model using system identification method and compare the rise time, settling time, and overshoot of original input source with tuned signal by varying responses time and transient behaviour in PID controller tuner. Road slope is one of the factors that influence road crash occurrences, and it is essential to have good configuration of throttle and brake system. A system identification method used to obtain transfer function from default model where a PID controller can be tuned from the transfer function then applied in the full model. Various input and output variable used to train a transfer function and validate in the system identification toolbox in MATLAB to get the best-fit transfer function according to the default responses. The response of tuned controller model will be analysed and compared towards the default controller model. The model of the tuned PID controller forstep input managed to satisfy the desired response compared with the drive cycle source, it does not manage to satisfy the desired response.
