Abstract:
1. A steering test rig for performing a durability test with a steering device, the steering test rig comprising: at least one motion actuator adapted to move the steering test rig according to a motion control signal; at least one force actuator adapted to actuate the steering test rig according to a force control signal; at least one position sensor adapted to derive an actual motion value signal of a motion of the steering device; at least one force sensor adapted derive an actual force value signal of a force on the steering device; and a control device adapted to receive the actual motion value signal and the actual force value signal and compute the motion control signal and the force control signal, the control device further adapted to output the motion control signal to the at least one motion actuator and the force control signal to the at least one force actuator, the control device comprising: a control unit adapted to compute the motion control signal from a motion reference signal, from a motion actual value signal of the position sensor and from a stored motion correction signal and compute the force control signal from a force reference signal, from a force actual value signal of the force sensor and from a stored force correction signal, comprising
