“…Wang et al [35] have compared the vibration isolation performances of the convalescent-wheelchair robot with and without a vibration-reducing device, and conducted the sensitivity analysis of the vibration responses to the important dynamic parameters. Although there exist many works dealing with the development of active and semi-active suspension systems, such as the researches of Van der Sande et al [33], Anandan and Kandavel [2] and others [4,8,20,29,31] on multiobjective optimisation related to passenger comfort and road holding of ground vehicles, few dealt with multi-objective optimisation of electric wheelchairs. The focus was on improving control automatisms using genetic algorithms, in contrast with the studies of Sankardoss and Geethanjali [28], Ahmad et al [1] and Dad et al [5].…”

The paper addresses the multi-body modelling of an electric wheelchair using Jourdain’s principle. First, a description of the adopted approach was presented. Next, the mathematical equations were developed to obtain the dynamic behaviour of the concerned system. The numerical computation was performed with MATLAB (matrix laboratory: a high performance language of technical computing) and validated by MBD (Multi-Body Dynamics) for Ansys, a professional multi-body dynamics simulation software powered by RecurDyn. Afterwards, the model was treated as an objective function included in genetic algorithm. The goal was to improve the ride quality and the road holding as well as the suspension workspace. The multi-objective optimisation aimed to reduce the Root-Mean-Square (RMS) of the seat’s vertical acceleration, the wheels load and the workspace modulus by varying the bodies’ masses, the spring-damper coefficients and the characteristics of the tires. Acceptable solutions were captured on the Pareto fronts, in contrast to the relatively considerable processing time involved in the use of a random road profile generated by the power spectral density (PSD). During the process, the compatibility and the efficiency of Jourdain’s equations were inspected.

“…Unlike passive suspension systems, semiactive and active ones can continuously change the vibration energy of the vehicle body induced by road excitation; therefore, they have a potential to improve the ride comfort and vehicle maneuverability. In the field of mechatronics, theoretical and experimental investigations of several types of suspension systems, including passive (Williams, 1997), semiactive (Ahmadian and Pare, 2000; Verros et al, 2005; van der Sande et al, 2016; Yin et al, 2016), and active suspensions (Dong et al, 2016; Göhrle et al, 2015; Huisman et al, 1993; Rath et al, 2017; Sun et al, 2013) have been performed. The dynamics of the active suspensions possess inherent complexity due to some kind of uncertainties and stochastic surface roughness.…”

In this paper, a new approach for stochastic logarithmic variable structure control has been proposed to create a compromise between reaching phase duration and response rate of the stochastic suspension system. The asymptotic stability with probability one for the closed-loop suspension system has been analyzed by Lyapunov method. Some practical considerations in proving theorems are uncertain parameter variations, environmental matched disturbances, actuator degradation, stochastic environmental mismatched disturbances, which is a representative of the change in road profile with time, and unmodeled dynamics. Finally, by regulating a specific parameter, the simulation results corroborate the advantage of the proposed controller in managing and reducing the sensitivity of the closed-loop system. Also, compared with other sliding surfaces of past researches, the designed sliding variable minimizes a certain performance function and therefore provides better performance for the closed-loop system, which is also verified in the simulation results.

“…A number of new SH algorithms have been implemented and compared experimentally with the simulation results, proving the applicability of SH algorithms. [17][18][19][20] Recently, based on the variety of SH Van Der Sande et al 21 proposed a rule-based controller for a semi-active suspension to reach minimal vertical acceleration, which performed much better than SH and ADD and slightly better than the mixed SH-ADD. Another controller was proposed by Nie et al, 20 achieving a good trade-off between ride quality and road-holding, by using the properties of the invariant points and employing a novel frequency selector.…”

In this work, a novel distribution-based control strategy of semi-active vehicle suspensions is tested under different conditions. The novelty lies in the use of an appropriate threshold in the operational condition of the control algorithm, with which the operational conditions severity is quantified and the state of the damper is controlled according to the magnitude of the operational conditions and not their sign. The value of the threshold depends on the vibrations induced to the sprung mass by the road profile. In order to be evaluated, the operational conditions of the algorithm are fitted to a t-student distribution. The cumulative distribution function of this distribution is used in order to decrease the fraction of the sample operating with the damper’s stiff state. The strategy is applied to traditional SH control algorithms and is tested using a quarter car model excited by different road excitations. A sensitivity analysis for various threshold values is performed, investigating the impact of adopting the cumulative distribution functioned (CDF) controller to various performance metrics. The results illustrate an increase of up to 13% in the ride comfort of the passengers and increase of 6% in the road holding of the vehicle. Both are achieved by minimizing the switches of the damping ratio up to 80%.
