PURPOSE:To assuredly reduce the width of the limit cycle and to eliminate the evil effect caused by a play, by applying intermittently a signal having a specific time width and size to an operating device. CONSTITUTION:While the operation signal is applied to an operating device having a play, a compensation signal, which has the time width (t) much shorter than the time constant T0 of a feedback control system (for instance t<T0/5) and has the size H equal to or larger than the play of the operating device, is applied intermittently and with a time interval T (for instance T>5T0) which is much longer than the constant T0 of the feedback control system. As a result, the state of the device having a play has always a drift to either one side. |
