ROTARY ACTUATOR SUITABLE FOR GENERATING A VARIABLE RESISTANT TORQUE ON THE CONTROL WHEEL OF A CONTROL SYSTEM, ACCORDING TO AN ADAPTIVE LAW.

摘要

P The actuator according to the invention comprises, coupled to the rotary shaft (2) of the steering wheel (1), a kinematic chain comprising an angular position sensor (5), a torque limiter (9), a device (10) for measuring the resulting torque exerted on the axis (2), and an electric motor (8) adapted to apply on said shaft (2) a variable torque as a function of a control signal. BR/ A subtracter (S2), which receives a setpoint signal (C0) produced by a computer and the signal supplied by the measuring device (10), delivers an error signal (epsilon) used to carry out the command of the motor (8). BR/ The invention is particularly applicable to the creation on the steering wheel of a vehicle, artificial sensations. / P
