Abstract
A variable feel side stick controller for producing and regulating feedback orces on a side stick for optimum pilot response. The controller consists of the floating table assembly which transfers the three-dimensional motion of the side stick into a two-dimensional motion. A series of hydraulic cylinders mounted on the floating table which are connected to a series of hydraulic circuits regulate the feedback forces produced on the side stick. The instantaneous position of the side stick can be determined from a series of linear potentiometers coupled to the hydraulic cylinders or from a series of force transducers connected to the hydraulic circuits. The two-dimensional floating table assembly allows use of a cam and cam follower arrangement which allows the force field to be varied with the shape of the cam.
