An improved two-axis electromechanical controller for controlling a dynamic process is described herein and comprises a hand grip coupled to two gimbal elements having mutually perpendicular axes of rotation, adjustable spring centering means mounted eccentric to the said axes of rotation and an adjustable counterweight for resisting displacement forces on the grip and restoring the grip to a reference position when a displacement force is removed, and electrical transducers for sensing the angular positions of each gimbal element. The force versus displacement relationship of the controller of the described invention is smooth and monotone, and may be adjusted to be substantially linear.
