In this study 3-DOF quarter car model with the three bumps on rigid road, assumption has been modeled non-random irregularity. To reduce excessive vibrations occurred vehicle body, an active suspension system linear actuator considered. Moreover, to control actuator, adaptive neuro-fuzzy algorithm is designed. The training and testing data of ANFIS obtained from Proportional Integral Derivative...

Novel lumped dual-frequency impedance transformers (DFITs) for arbitrary frequency dependent complex loads (FDCLs) are synthesized using the concepts of capacitive and inductive inverters. Such a dual-frequency impedance transformer is constructed with one Pi-shaped lumped inverter and two shunt susceptance blocks at two sides, and get simplified after susceptance merging. The shunt susceptance...

The design strategy of an adaptive Proportional-Integral-Derivative (PID)-like fuzzy controller for anti-slip Quarter-Car robotic system is proposed. proposed control constructed by two loops, external one lineal speed and internal loop current control. A motion profile used to follow a trajectory. slip computed, such as the difference between linear velocity given S-curve longitudinal calculat...

Despite the ever-increasing computational power of modern processors, the reduction of complex multibody dynamic models remains an important topic of investigation, particularly for design optimization, sensitivity analysis, parameter identification, and controller tuning tasks, which can require hundreds or thousands of simulations. In this work, we first develop a high-fidelity model of a pro...

the control of car following is essential due to its safety and its operational efficiency. for this purpose, this paper builds a model of car following behavior based on armax structure from a real traffic dataset and design a model predictive control (mpc) system. based on the relative distance and relative acceleration of each instant, the mpc predicts the future behavior of the leader vehic...

Ride quality is concerned with the feel of the passenger in the environment of a moving vehicle. It is one of the key indices in determining comfort levels of a vehicle. Although, “ride comfort” evaluation is subjective in nature, researchers have developed mathematical models to study and evaluate vehicle ride performance. Some popular models for vehicle ride analysis are – quarter car model, ...

This paper presents multi-layer feedforward neural network-based identification and approximate predictive controller (NNAPC) for a two degree-of-freedom (DOF), quarter-car servohydraulic vehicle suspension system. The nonlinear dynamics of the servo-hydraulic actuator is incorporated in the suspension model. A suspension travel controller is developed to improve the ride comfort and handling q...
