refining the spring stiffness of a motor alternate directions
refining the spring stiffness of a motor alternate directions
(OP)
Hi
I have a control system in which i am using a DC motor and have designed a controller to compare the output of torque and position in order to make the motor shaft mimic the action of a spring however i want different amount of spring stiffness in the clockwise anticlockwise direction any ideas i'm baffled myself??
Thanks in advance any help very much appreciated

A simple diode would introduce some non-linearity but I believe it can be done linear-fashion using op-amp circuits.
