<p>The motion of a member such as a simulator plane (40) and a 'virtual reality' cabin, or a vehicle, is controlled by apparatus comprising one or more preferably electromagnetic actuators (30) disposed between the member (40) and a ground level (10), and a control arrangement for providing signals to the actuator whereby to cause the actuators to generate thrust. In order to allow the motion of the member (40) to be influenced by factors such as the movement of a user on the simulator plane, or the detection of other movements, the apparatus further comprises means for monitoring characteristic of the relative positions or movements of the member and the ground level (10) or the forces between the ground level, the actuator and the member, and providing signals indicative of said characteristics. The control arrangement is responsive to signals provided by the monitoring means and comprises means for generating or modifying the control signals to be provided to the actuator. By controlling the motion of a member in this way, it is possible to make motion systems such as 'virtual reality' system more convincing. It is also possible to construct stabilizing systems such as active suspension systems (85) for vehicles.</p> |
