Publication number: 20200032727Abstract: A control system includes an electronic control unit including a feedback controller and a reference governor. The feedback controller is configured to determine a value of control input such that a value of control output approximates a target value. The reference governor is configured to calculate, with a prediction model, a predicted maximum value of an overshoot amount of the control output that overshoots from the target value. The prediction model is derived assuming that an n-th delay (n is a natural number) occurs in a response of the control output. The reference governor is configured to calculate the target value by correcting the provisional target value of the control output based on the predicted maximum value so as to increase a degree of satisfaction of a constraint condition with regard to the control output.Type: ApplicationFiled: June 25, 2019Publication date: January 30, 2020Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hayato NAKADA, Takeshi SANO
