ACTUATOR CONTROLLER OF WORKING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide an actuator controller securely reducing jerking motion generating in a rapid operation by a simple control to eliminate a shock. SOLUTION: The working machine is provided with an actuator 6 driving the movable part of the working machine, an operation lever for operating the actuator 6, and a controller 9 controlling the actuator according to an operation instruction of the operation lever. The controller 9 is provided with a target speed calculator 9a calculating the target speed of the actuator based on the operation quantity of the operation lever and a jerk regulation processing part 9b calculating a jerk expectation figure by two-step differentiation of the calculated target speed and judging whether the calculated jerk expectation value exceeds a specified value and correcting the target speed so that the jerk expected value is not higher than the specified value when the jerk expectation value is judged to be higher than the specified value.
