PROBLEM TO BE SOLVED: To provide a machine controller that can stably control even a controlled machine including an error element. SOLUTION: The machine controller comprises first filter means 3a, second filter means 3b, adding means 3c, subtracting means 3d and gain means 3e. The first filter means 3a have frequency characteristics that remove a range near the natural oscillation frequency of a controlled machine. The second filter means 3b have frequency characteristics that pass the range near the natural oscillation frequency of the controlled machine. COPYRIGHT: (C)2004,JPO
