Abstract
A method of controlling an actuator includes developing a sequence of actuation commands S(t)=C(t, t), C(t, t), . . . , C(t, t) obtained from data sensed before time tfor controlling the actuator at different time intervals (t, t), (t, t), . . . , (t, t). The sequence of actuation commands is transmitted to and stored in memory of an actuation ECU, which then applies the actuation command for time interval (t, t). If a fault affects a sensor, a control ECU or data communication therebetween, the actuation ECU will not receive an updated sequence of actuation commands S(t) at time t. If the updated actuation command sequence, the actuation ECU applies the actuation command for the time intervals (t, t), . . . , (t, t) from the sequence of actuation commands S(t) that is stored in the memory of the actuation ECU.
