Abstract
An adaptive control system, for a plant such as a servo motor, a heat pump and the like where its input distribution matrix is known and the number of effective inputs is the same as the number of independent outputs, comprising: an unknown dynamics value production circuit for producing an unknown dynamics value by adding a derivative value of a detected state output value of said plant, negative quantity of multiplication of an input value of said plant and an input distribution matrix value of said plant, and negative quantity of a known value of said plant; a non-identity filter, except for a time delay element, for producing a filtered unknown dynamics value which is close to but not exactly the same as said unknown dynamics value; a control input value production circuit for producing a control input value to said plant by using said filtered unknown dynamics value.
