Active vibration control of a forklift´s steering wheel system by the receptance method

This article describes the application of the receptance method vibration control technique on the steering wheel system of a forklift. Numerous advantages of the receptance method over conventional matrix methods as there is no need to know or to evaluate the M, K, C matrix since the determinant of the controller gains are expressed in terms of the receptance measured through experiment. With this method, several poles in the steering wheel system of a forklift which may produce resonance at idle speed of the engine were replaced to predetermined value. Model computation and simulation were carried out with PRO/E software and controllers were implemented using Matlb/Simulink. Locations of the open- and closed-loop poles in the complex plane are obtained to verify that the required assignment of poles had taken place.
