Abstract
Abstract An adaptive control system for vehicles using a time delay control method which applies a reference model for giving desired response characteristics, assums that terms of an unknown section such as for variations of plant dynamics are constant for a minute time period, and estimates this variation of the unknown section to calculate a control input that follows said reference model.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
214 words
An adaptive control system for vehicles comprising, for a system in which plant dynamics change: an actuator (16, 210) for controlling a controlled variable such as oil pressure, position and velocity; a detection means (12) for detecting an output of a plant which is driven by said actuator (16, 210); a desired value setting means (13) for setting a desired value of said controlled variable; a reference model setting means (15) for setting response characteristics of a plant output following said desired value to a desired characteristic model; and a controlled variable calculation means (14) for applying a control input to said actuator (16, 210) calculated by using a detected value from said detection means (12) and said desired value so that the plant output has response characteristics as a model (32) set by said reference model setting means (15); wherein control functions relating to the control input operation of said controlled variable calculation means (14) are given by the time delay control method in which it is assumed that a term of unknown section is constant for a minute period of time such as for variations of plant dynamics, so that said control input is calculated to obtain said desired response characteristics based on an estimated value of said term of unknown section.
