“…Hence, and are going to be replaced by a set of six elements ( 0 , 0 , and hysteresis front , 0 , 0 , and hysteresis rear ) that represents two MR dampers in order to vary suspension's damping factor. For the present study, front and rear dampers have similar characteristics, and they are modelled via Bouc-Wen approach [6], as reported in Félix-Herrán et al [28]. The resulting suspension is depicted in Figure 2.…”

“…Model. Following the approach in [28], a Takagi-Sugeno fuzzy model [31] needs to be obtained in order to synthesize a controller. The first step is to rearrange the equations of motion in such a way that nonlinearities can be clearly identified [25] and, if possible, to group them into one single nonlinearity.…”

“…Simulation results based on realistic data support the theoretical work in Section 3. The one-half vehicle suspension parameters are in Table 1. MR damper numerical data are the same ones employed for the one-quarter case in Félix-Herrán et al [28], and = 1.0 × 10 6 m −2 , = 1.2 × 10 6 m −2 , and = 15 are taken from a real MR damper characterization in Sireteanu et al [30]. It is worthwhile to mention that real MR dampers do not respond instantaneously to current changes [6].…”

This work presents a novel semiactive model of a one-half lateral vehicle suspension. The contribution of this research is the inclusion of actuator dynamics (two magnetorheological nonlinear dampers) in the modelling, which means that more realistic outcomes will be obtained, because, in real life, actuators have physical limitations. Takagi-Sugeno (T-S) fuzzy approach is applied to a four-degree-of-freedom (4-DOF) lateral one-half vehicle suspension. The system has two magnetorheological (MR) dampers, whose numerical values come from a real characterization. T-S allows handling suspension’s components and actuator’s nonlinearities (hysteresis, saturation, and viscoplasticity) by means of a set of linear subsystems interconnected via fuzzy membership functions. Due to their linearity, each subsystem can be handled with the very well-known control theory, for example, stability and performance indexes (this is an advantage of the T-S approach). To the best of authors’ knowledge, reported work does not include the aforementioned nonlinearities in the modelling. The generated model is validated via a case of study with simulation results. This research is paramount because it introduces a more accurate (the actuator dynamics, a complex nonlinear subsystem) model that could be applied to one-half vehicle suspension control purposes. Suspension systems are extremely important for passenger comfort and stability in ground vehicles.

A fuzzy-H ∞ control, improved with weighting functions, has been designed and applied to a novel model of a one-half semiactive lateral vehicle (OHSLV) suspension. e herein contribution resides in the development and computation of an H ∞ controller with parallel distributed compensation (PDC) designed from a highly nonlinear system modelled via the Takagi-Sugeno (T-S) fuzzy approach. A fuzzy-H ∞ controller is synthesized for an OHSLV T-S fuzzy model of a suspension with two magnetorheological (MR) dampers including actuators' nonlinear dynamics. e realism of results has been improved by considering the MR damper's behaviours (viscoplasticity, hysteresis, and saturation) and the handling of the phase angle of the sinusoidal disturbance, not included in other reported work. Time-domain tests remark transient time achievements, whereas precise performance criterion indices in the frequency domain are employed to assess the generated outcomes. e proposed solution complies with all performance criteria compared with a benchmark passive average suspension that fails in satisfying most of the performance criteria.

“…However, the researches only concerned under the vibration excitations of the rigid road surface roughness. Nowadays, the combined control methods such as PID-Fuzzy [12,13], H inf -Fuzzy, or Skyhook-NFLC control [14,15] were applied to control the damping forces for the semi-active suspension system or active suspension system of vehicles and seat. The results showed that the ride comfort was significantly increased by using the above control methods.…”

To improve the soil compactor ride comfort, a combined control method of Fuzzy and PID control is proposed to control the cab isolation system of soil compactor based on the non-linear vehicle dynamic model. The vibration excitation sources are concerned by the vibrator drum and elastoplastic soil (EPS) interactions in the compression process. The power-spectral-density (PSD) and weighted root-mean-square (RMS) of acceleration responses of both the vertical driver's seat and pitching cab angle are chosen as the objective functions. The research results show that both the PSD and weighted RMS values of the vertical driver's seat and pitching cab angle are significantly reduced by using the PID-Fuzzy control under various EPSs in the low-frequency region, especially on the EPS with high-density.
