Abstract: A motion simulation system includes actuators having a planetary gearbox engaged with and driven by a servomotor engaged with a crank. A connector rod has a proximal end engaged with the crank of each actuator, and a distal end engaged with a top plate configured to attach to a platform assembly. A control system is operable with each electric servo motor of each actuator for delivering control for providing a simulated motion to the top plate. Control data is sent to the servomotors using a msec data send and receive rate, with internal processing within the nano-second range. Such update rates coupled with a real time, dynamically responsive motion controller results in a desirably smooth and accurate simulator motion. The control system includes a washout filter for transforming input forces and rotational movements. One to six degrees of freedom systems having smooth performance with high payload capability are provided.
