Shift control apparatus and shift control system provided with the same

摘要

A shift control apparatus (1) for a transmission, by which a predetermined shift stage among plural shift stages is established in response to operation of a shift and select operations mechanism and a shift stroke (y(t)) determined by the shift and select operations mechanism is controlled to correspond to a target shift stroke (r(t)), whereby the shift control apparatus (1) includes
a PID controlling means (Cpid(s)) for applying a PID control to a deviation between the target shift stroke (r(t)) and the shift stroke (y(t));
a reference model controlling means (M(s),AMP1) for controlling the shift stroke (y(t)) to be approximated to an ideal response (rstd(t)),
a stabilizing controlling means (AMP2) for stabilizing a model of a controlled object (P(s)) through a feedback loop corresponding to a shift operation of the shift and select operations mechanism; and
a disturbance observing mechanism (NOB) for eliminating a disturbance by feed backing an estimated disturbance value (vobv,(t)) calculated based upon an input to the model of the controlled object and an output from the model of the controlled object (P(s)).
