Summary:PURPOSE:To converge a position into an objective position quickly, by providing a switch for an input and output each of an integrator and also a signal system initially setting a signal corresponding to an objective value to the integrator and a switch switching the signal system. CONSTITUTION:When an electrostriction element 1 is displaced and closes to an objective, a position deviation closes to 0. When the deviation is smaller than a set level, an output Sw of a switch changeover circuit 10 goes to 1, a switch 9 is opened and switches 6, 7 are closed. Thus, an integration system is also operative, but since a value in which an integration output I0 might be converged finally is preset to the integrator 5, the sum with a proportional component output P0 is almost the same value. Thus, a displacement signal V0 is smoothly converged into the objective value without overshooting and quick settling time can be obtained.
