Active suspension system with linear electric motor

Suspension system is an important part of the car design, because it influences both the comfort and safety of the passengers. In this paper an active suspension using linear electric motor is designed. This article is also focused on experiments with active suspension - developing an appropriate input signal for the test bed and evaluation of the results. Second important aspect of the active suspension design is energy demand of the system. Modification of the standard controller which allows changing amount of energy required by the system has been designed. Performance of the modification was verified taking various experiments.
