PROBLEM TO BE SOLVED: To provide a linear induction motor controller which can make the same control as the vector control calculation for a rotating three-phase induction motor by compensating the change of its constants on the basis of varying of gap. SOLUTION: This controller has a constant compensator 11, which compensates mutual inductance change caused by the change of the gap between the primary 6 and the secondary 12 by obtaining the relations of the gap and the mutual inductance, which is the equivalent circuit constant of the motor, and a linear induction motor control for controlling the motor on the basis of the output from the above constant compensator 11. |
