The main purpose in the study of boom suspension is to investigate the possibility of using an active suspension instead of the traditional passive system. In addition to the improved spraying result, an active system would make the operator's task much easier. The project compares the possible perforamnce of an active and passive boom suspension. A model has been made of an advanced active system, that combines a traditional trapezoid, with a spring pendulum system. The system can be described with a linear forth order model. The system has been the foundation for an active suspension, that combines a hydraulic actuator and a spring. A closed loop lead compensator including a set of distance transducers has improved the performance significantly. The active system has been simulated on a constructed srface.
