MIX-1-SENSOR: A CONTROL STRATEGY FOR SEMI-ACTIVE SUSPENSION.

The topic of this paper is the design and analysis of a control strategy for semi-active suspensions in road vehicles. Currently used closed-loop control strategies (like the Sky-Hook damping) require at least two sensors for each suspension. In this paper a simple but very innovative algorithm is proposed, capable of providing quasi-optimal performance using a single accelerometer. The starting point of this work is the mix Sky-Hook Acceleration-Driven-Damper control algorithm, which has been recently developed and proposed. Starting from that idea, the single-sensor algorithm is derived. This algorithm pays a little performance price with respect to the mix SH-ADD algorithm, while guaranteeing cost-reduction and augmented reliability. In this work the theoretical development is complemented with extensive simulation results using a 2-wheels vehicle simulator comprising an accurate modelling of the semi-active dampers. Some final experimental results are also provided.
