Abstract

A control algorithm verification platform was built based on a rapid prototype controller to provide fast, effective verification of magnetorheological semi-active suspension control algorithms. The kingpin angle and the space angle of the lower arm were considered in the 1/4 vehicle suspension system model. The acceleration sensor and the body height sensor were mounted on the suspension. An LMS Test Lab system was used to collect and analyze the suspension system vibration data. The rapid prototype controller was used as the carrier for developing and debugging the control algorithms. Platform verification tests were used to verify the algorithm development, the control process monitoring, the control algorithm adjustments, and the quantitative analyses. This platform meets the design goals and is convenient, fast, and effective for developing, debugging, and verifying semi-active control algorithms.
