Inventor: TAKENAKA TORU
IPC: G05D3/12
Filed: 1992-04-30
Abstract: PURPOSE:To reduce the energy consumption of an actuator at the time of holding by reducing a control gain after real displacement becomes a standstill. CONSTITUTION:In the driving method of the actuator, which displacement- controls a mechanism with friction and holds a target value against the static load of gravity, a displacement command for the target value is given while the control gain is raised, and the control gain is reduced after real displacement is standstill.
