An estimated rotation angular velocity squarer0 and an estimated secondary resistance Hr0 are processed using a first feedback gain H1 under a condition that a first state deviation E1 is in phase with a quadrature component of an estimated secondary magnetic flux squarer01. An estimated primary resistance Rs0 is processed using a second state deviation H2 under a condition that a second state deviation E2 is in phase with an estimated primary current 02. These values are used to control the speed of an induction motor without an angular velocity detector. |
