A Farm Equipment Manufacturer has a need to actively reduce the vibration of the operator's seat using an electrodynamic actuator. The frequency of operation varies from 1 to 10 Hz. Your goal is to develop the active control system of the seat. The seat without control (no actuators or sensors) will be referred to as Uncontrolled Seat.
