1. A servo coupled hand control system comprising:
- coupled first manual control means and second manual control means for generating control signals in response to respective manual inputs, said first manual control means being a leading control means and said second manual control means being a following control means;
first position detecting means for detecting the position of said first manual control means and for generating a first position signal in response thereto;
first torque detecting means for detecting torque exerted on said first manual control means and for generating a first torque signal representative of said torque exerted on said first manual control means in response thereto;
first summing means for summing said first position signal and said first torque signal for generating a first torque error signal;
first controller electronics means for processing said first torque error signal to generate a command signal for said first manual control means to produce a predetermined force versus displacement characteristic for said first manual control means; and
second controller electronics means for receiving and processing said first torque signal from said first torque detecting means for generating a command signal for causing said second manual control means to track in position said first manual control means.

Abstract
A servo controlled system is provided for electrically coupling the motions and applied forces of pilot and co-pilot control sticks. Servo-coupling between the two control sticks is accomplished by detecting the position of the control sticks of respective controllers and/or detecting torque exerted on the control sticks. The position and torques signals are processed and employed in a feedback loop for each control stick to generate a feedback signal to motors to which the control sticks are mechanically coupled. The motors act on the control stick to simulate the feel of traditional mechanical controllers, and to cause the controllers to track each other'"'"'s movements.
