Abstract

In this paper we study an application of Passivity-Based Control (PBC) to a quarter car suspension system. We use Passivity-Based Control in the Brayton-Moser framework (BM-PBC) that has recently been developed for control of switching and non-switching electrical circuits. Via the usual mass-inductor and spring-capacitor analogy, we translate these results to the mechanical domain. This yields new rules for damping injection, where to place the virtual damping, and how to tune it. The concept of parallel damping from the electrical domain is now used for the quarter car model. The results are compared with the industrial sky-hook damping strategy, and in simulation the parallel BM-PBC outperforms the sky-hook damping strategy.
