“…In this section, the parameters of the virtual reference are optimized, and a simulation is conducted to verify the control performance of the designed VRFF on the vehicle simulation software, IPG CarMaker. IPG CarMaker has been widely used for validation on vehicle stability and active/semi-active suspension control over the last decade [52][53][54][55]. Through the simulation, the objective functions for the virtual reference are compared to one another.…”

“…The drawback is these controllers have high frequency control actions which can have a negative impact on the actuators. Sliding mode control for active suspension system has been evaluated, for example, an optimization based sliding mode controller designed to provide the correct amount of force to the actuator, 12 a fuzzy sliding mode active disturbance rejection control, 13 a comparison of linear quadratic regulator and sliding mode control optimised based on particle swarm optimization. 14…”

Car suspensions have the job to keep the tires in contact with the road surface as much as possible, to deliver steering stability with good handling and to guarantee passenger comfort. Most modern vehicles have independent front suspension and many vehicles also have independent rear suspension. Independent suspensions are preferred instead of dependent suspensions for their better ride handling, stability, steering and comfort but they provide less overall strength and a complex design which increases the cost and maintenance expenses for such a suspension. For this reason, automotive engineers struggle to discover new suspension components or advanced control solutions. Taking a step forward in this direction, the paper presents in the beginning one of the well-known mathematical models of a quarter-car active suspension. The obtained model is then implemented in a MATLAB/Simulink simulation which compares multiple control solutions. The only feedback considered for each control algorithm is the measurement of the body acceleration. Among these investigated control algorithms is the adaptive harmonic control solution proposed by this paper. The controller generates a harmonic control signal with variable amplitude and frequency based on the body acceleration feedback. The comparison analysis shows that the proposed control solution demonstrates quite good potential, generating in some cases better results than the other control algorithms.

“…They guarantee better performances than passive isolation systems but typically require sensors and an electronic control unit. Active solutions are characterized by an actuation system based on hydraulic, direct-drive electromagnetic, electromagnetic hydrostatic, or geared electric motor technology [19][20][21][22].…”

The vibrations induced by the soil irregularities and other equivalent disturbances on agricultural tractors represent a major cause of disease for tractor drivers. The reduction of vibration exposure of operators is a topic of interest for the (Italian) National Institute for Insurance against Accidents at Work (INAIL). Several passive, semi-active, and active solutions are commercially available for the seat or the cabin suspension to isolate the driver from the vibrations. A prototype of a hydraulic active suspension system for the operator seat has been developed in the laboratories of INAIL. In this paper, nonlinear multi-physics modeling of the prototype has been carried after an experimental identification of the actuation system and specifically of the control valve parameters. The model is adjusted to retrace the system’s response and is used as a digital twin of the physical prototype to develop and optimize the control system. An equivalent simplified model is obtained to design a proper control strategy for the active suspension system. Finally, the controller is tested on the digital twin of the system to assess its performance in isolating vibrations.
