PROBLEM TO BE SOLVED: To provide an actuator controller which allows an output of an actuator to follow an instruction input from a host control part accurately.SOLUTION: In a motor controller 100, a microcomputer 10 sets an upper target rotation speed of a brushless DC motor 50. An intermediate control part 30, in order to allow an actual rotation speed of the brushless DC motor 50 follow the upper target rotation speed, generates a pseudo upper rotation speed obtained by increasing/decreasing the upper target rotation speed before inputting in an instruction input element 21 of a rotation speed control circuit 20 and inputs the pseudo upper rotation speed in the instruction input element 21. In response to the input of the pseudo upper target rotation speed, the instruction input element 21 outputs a lower target rotation speed which is a different value from the pseudo upper target rotation speed. In response to the input of the lower target rotation speed, an actuator control element 22 controls the brushless DC motor 50 by PI control. A following element 23 allows the actual rotation speed of the brushless DC motor 50 follow the lower target rotation speed. |
