Abstract
In a sensor system for an actuator, in particular a lifting column, a force sensor is configured to detect a total force acting on an actuator part. An acceleration sensor is configured to detect an acceleration of the actuator part. Accordingly, the sensor system has a processing device, which is configured to control a drive of the actuator for moving the actuator part on a basis of the detected total force and the detected acceleration.
Claims15
A sensor system for an actuator, the sensor system comprising:
- a force sensor configured to detect a total force acting on an actuator part mounted movably relative to an actuator base;
- an acceleration sensor configured to detect an acceleration of the actuator part;
- and
- a processor configured to control a drive of the actuator for moving the actuator part on a basis of the total force detected and the acceleration detected, said processor further configured to use the total force and the acceleration to determine a measure of a force exerted on the actuator part by a user for moving the actuator part and to control the drive on a basis of the measure of the force.
An actuator, comprising:
- an actuator base;
- an actuator part mounted movably relative to said actuator base;
- a drive for moving said actuator part;
- and
- a sensor system, containing:
- a force sensor configured to detect a total force acting on said actuator part;
- an acceleration sensor configured to detect an acceleration of said actuator part;
- and
- a processor configured to control said drive for moving said actuator part on a basis of the total force detected and the acceleration detected, said processor configured to use the total force and the acceleration to determine a measure of a force exerted on said actuator part by a user for moving said actuator part and to control said drive on a basis of the measure of the force.
A method for moving an actuator part of an actuator being mounted movably relative to an actuator base, which comprises the steps of:
- detecting a total force acting on the actuator part;
- detecting an acceleration of the actuator part;
- and
- controlling, via a processor, a drive of the actuator for moving the actuator part on a basis of the total force detected and the acceleration detected, wherein the processor is configured to use the total force and the acceleration to determine a measure of a force exerted on the actuator part by a user for moving the actuator part and to control the drive on a basis of the measure of the force.
