Abstract
A system for positioning an object, having a fixed base, a support for the object, an actuator for applying a force to displace the support relative to the fixed base, a sensor for measuring the load force on the support, and a controller for processing the measured load force to control the position of the support and/or damp at least one resonance frequency of the system. A method of controlling the system is also provided.

A system for positioning an object, comprising:
- a fixed base;
- a support for the object;
- an actuator for applying a force to displace the support relative to the fixed base;
- a sensor for measuring the load force on the support, and
- a controller for processing the measured load force to control the position of the support and/or damp at least one resonance frequency of the system.
A method of controlling a system for positioning an object, the system comprising a fixed base, a support for the object and an actuator for applying a force to the support, the method comprising the steps of:
- actuating the actuator to apply the force to displace the support relative to the fixed base;
- measuring the load force on the support, and
- processing the measured load force to control the position of the support and/or damp at least one resonance frequency of the system.
