US 5,209,661 A · Motor control desired dynamic load of a simulating system and method

Abstract

An apparatus and method for simulating a desired response in accordance with an external applied force. The apparatus includes a member which is responsive to the applied force, an actuator coupled to the member for exerting a torque on the member, a force sensor for detecting the applied force, and a torque sensor for detecting the torque exerted by the actuator. Signals from the force sensor are used to determine the system response based upon a desired relation. The force sensor signals also are used to determine the actual system response based upon the physical characteristics of the apparatus. The detected torque is compared with the desired and the actual system response, and as a result of the comparison the torque exerted by the actuator onto the member is adjusted accordingly so that the member performs the desired system response. The actuator is preferably an electric motor so that the apparatus can simulate any desired response, notwithstanding the physical characteristics of the system.
