“…H ∞ strategy has been intensively used in the active seating suspension system control [75]. In [76] the author used the static feedback H ∞ controller with friction compensation based on the seat acceleration, suspension relative displacement and suspension relative velocity. An acceleration measurement-based observer was designed to estimate the friction.…”

Drivers of heavy trucks are exposed to large amounts of vibration which can lead to serious health risks. Many suspension systems/methods can be used to isolate these transmitted vibrations, such as vehicle suspension systems, cabin suspension systems and seating suspension systems. The central idea of the work is to identify the research gaps and raise our future research questions in this specific area. The novelty of this paper is proposing a model predictive controller for active vibration control of seating suspension systems. A systematic literature review of the existing work of the vibration control of seating suspension systems has been conducted. Various control techniques that are used in the seating suspension systems have been summarized and evaluated. This paper focusses on the biodynamic model of the driver and seat for the first step needed in the design of the seating suspension system. Then, it illustrates the different types of the system vibration controls and their performance evaluation methods. At the end, the paper details several active seating suspension systems including their actuation system structures and control algorithms which are used in the heavy vehicle trucks.

“…A new active seating vibration reduction structure ( Figure 12) was proposed in [57][58][59][60]. This seating system is based on the common scissor-like structure of commercial vehicle seating systems, using an inexpensive conventional rotary electric motor instead of an expensive linear motor as the actuator.…”

“…In another study, [58] proposed an H-infinity controller with friction compensation to control the previously mentioned active seat suspension. Due to the usage of the friction observer based on the acceleration measurement, the H-infinity controller can be more sensitive to the response of vibration excitation and can also improve the vibration control performance.…”

As a major device for reducing vibration and protecting passengers, the low-frequency vibration control performance of commercial vehicle seating systems has become an attractive research topic in recent years. This article reviews the recent developments in active seat suspensions for vehicles. The features of active seat suspension actuators and the related control algorithms are described and discussed in detail. In addition, the vibration control and reduction performance of active seat suspension systems are also reviewed. The article also discusses the prospects of the application of machine learning, including artificial neural network (ANN) control algorithms, in the development of active seat suspension systems for vibration control.

“…A negative stiffness seat suspension is proposed for a passive seat suspension to have better performance in resonance frequency [2]. The active seat suspensions has been proposed with different actuators, such as the electromagnetic linear actuator [3], the hydraulic absorber [4], the pneumatic actuator [5] and the rotary motor [6][7][8]. The active seat suspension has best performance in improving ride comfort, but the high energy consumption is the main issue for its application.…”

In this paper, an energy saving variable damping seat suspension system is designed, manufactured and validated. A controllable electromagnetic damper (EMD), which consists of a permanent magnet synchronous motor (PMSM), a 3-phase rectifier, a metal-oxide-semiconductor field-effect transistor (MOSFET) switch module, an external resistor, a diode, and a capacitor, is designed and tested firstly. The EMD is integrated with a planetary gearbox to amplify its torque output, and both of them are installed on the centre of the scissors structure of a seat suspension. The EMD's damping property can be controlled by exerting pulse width modulation (PWM) signal with different duty cycles on the MOSFET switch module. By analysing the EMD test results and the seat suspension's kinematic, the controllable damping of the EMD is derived from 115.68 Ns/m to 669.74 Ns/m. A control method for vibration isolation is proposed considering that the generated damping force is reverse to the suspension's relative velocity, and its value is related to both the damping coefficient and the relative velocity, thus the desired control force can be partially achieved by the variable damper. The proposed variable damping seat suspension and its controller are validated on a 6-degree of freedom (6-DOF) vibration platform in both frequency domain and time domain. The test results show that the controlled variable damping seat suspension has better performance in vibration isolation than the proposed seat with highest and lowest damping, and the conventional passive one. In the meantime, the RMS value of the system harvestable power is 1.492 W, and the power consumption of the PWM control signal is very few. Therefore, this variable damping seat suspension can improve the ride comfort with ignorable energy cost.
