The Lotus Active Suspension system overcomes many of the deficiencies of a conventional suspension by replacing the springs, dampers, anti-roll bars, etc. by four irreversible hydraulic actuators. Measurements of a range of vehicle and actuator parameters are then used to control the position and velocity of each actuator in real time so as to synthesize an 'ideal' vehicle suspension. This paper contains an outline history of the Lotus system, a discussion of the requirements for the controller, an introduction to the family of DSP's selected, and descriptions of two active suspension controllers which incorporate Digital Signal Processors. The paper concludes with a description of a possible production standard control system.
