| Summary: | 碩士 === 國立臺北科技大學 === 車輛工程系所 === 96 === A multi-input single-output (MISO) controller using model predictive control is proposed for idle speed control in this thesis. The spark advance and idle-air-control valve opening are simultaneously employed as control inputs for maintaining the desired idle speed. Unlike the conventional algorithm which uses the idle-air-control (IAC) valve as the only actuator. The recursive least square technique is employed to identify the engine as a first-order linear model. A nonlinear engine model established in Matlab/Simulink is used to evaluate the proposed and conventional algorithms. The proposed algorithm is also implemented on a scooter engine using the electronic control unit from Mototron. Both simulation and experimental results show that the proposed algorithm has less speed deviation than the conventional one under the presence of torque disturbances and that of model uncertainties.
