Transmission control system

摘要

A transmission control system is capable of promptly compensating for a disturbance attributable to a mechanical interference that takes place in a selecting operation so as to quickly complete the selecting operation. An adaptation disturbance observer (57) provided in a selection controller (51) calculates a disturbance component term (C1_S1) in a model equation of a selecting mechanism (40) for each control cycle of the selection controller (51). An equivalent control input calculator (44) of a sliding mode controller (55) uses the disturbance component term (C1_sl(k)) calculated by the adaptation disturbance observer (57) to calculate an equivalent control input (Ueq_sr). An adder (45) adds a reaching law input (Ursch_sl(k)) calculated by a reaching law input calculator (43) and the equivalent control input (Ueq_sr) to calculate a control value (Vsl) of a voltage to be applied to a selection motor (12) of the selecting mechanism (40).
