“…In [16], it proposes an PID-type sliding surface to modify the conventional sliding mode controller. In [17], it adopts an saturation function instead of the switch function as the sliding-mode control law. And a integral sliding-mode control method, which is a combination of the nominal control and the discontinuous feedback control, is presented in literature [18] to solve the chattering problem.…”

“…Therefore, reducing chattering is an important problem in the application of the sliding mode controller. The problem of chattering has been extensively studied and several approaches for chattering suppression have been proposed in literature [11,12,[15][16][17][18]. In [11,12], it takes use of the second-order sliding-mode control methodology to design controllers.…”

Considering the nonlinear characteristics, model uncertainties and the time-varying road conditions of ground vehicles, a novel traction controller for ground vehicles is presented using nonlinear robust modified sliding mode control method to solve the problem of skid braking and spin acceleration. The current wheel slip could be controlled at the optimal value using this method, so that it could improve the safety and stability of ground vehicles in slippery road conditions. Due to the optimal value of the wheel slip depends on road conditions, the so-called Burckhardt's tire model is adopted to make online calculation. In order to validate the effectiveness of the proposed method, simulations in different road conditions are carried out, and a series of simulation results indicate that the wheel slip tracking controller could obtained fairly good performance.

“…Important factors influencing hysteresis pressure losses in a hydraulic brake system are analyzed by Tretsia et al, 10 while a methodology for estimating the flow coefficient as a function of the Reynolds number is presented by Valds et al, 11 who exploit a parametric computational fluid dynamics simulation of the flow rate in hydraulic valve systems. A first-order model with the same time constants for increase and decrease mode is presented by Baek et al 12 The values of these parameters are unknown and no justifications are reported to consider them constant. A paper presented by Moaveni and Barkhordari 13 identifies single-input (pressure of master cylinder), single-output (brake calipers pressure), linear, minimum-order models for the hydraulic unit in the increase and decrease modes by employing the experimental data of a test automobile and using a least-square method and a prediction error method.…”

This paper introduces a method to characterize the dynamic behavior of a normal production hydraulic brake system through experiments on a hardware-in-the-loop test bench for both modeling (part I) and control (part II) tasks. The activity is relative to the analysis, modeling, and control of anti-lock braking system and electronic stability control digital valves, and is aimed at obtaining reference tracking and disturbance-rejection performance similar to that achievable when using pressure proportional valves. The first part of this two-part study is focused on the development of a mathematical model that emulates the pressure dynamics inside a brake caliper when the inlet valve, outlet valve, and motor pump are controlled by digital or pulse width modulated signals. The model takes into account some inherent nonlinearities of these systems, e.g. the variation of fluid bulk modulus with pressure, while inlet and outlet valves together with the relay box are modeled as second-order systems with variable gains. The hardware-in-the-loop test rig is used for both parameter estimation and model validation; the parameters and model will be used for the control strategy development presented in the second part of this study.

“…A number of studies have modelled the brake system for wheel slip control over the last three decades. [17][18][19][20][21][22][23][24][25][26][27][28][29] Khan et al 18 developed an analytical dynamic model for the brake system of a vehicle. They validated the modelling results by testing a laboratory set-up of a brake system and compared the results with those of a computer-controlled brake system.…”

“…Tretsiak et al 26 analysed the factors influencing the hysteresis pressure loss in a hydraulic brake system. Baek et al 27 presented a 15-degree-of-freedom model for a vehicle and introduced first-order models with the same time constants for the increase mode and the decrease mode. They were unable to provide proof that the time constants of these two modes were equal, and the values of the time constants were unknown.…”

The present paper identifies single-input single-output linear minimum-order models for the hydraulic unit of an anti-lock brake system in the increase mode and the decrease mode. The input variable and the output variable in the models for the increase mode and the decrease mode are the pressure of master cylinder and the pressure of the brake caliper respectively. In the process of model identification, excitation signals are designed by introducing a novel method to change the states of the solenoid supply valve and the solenoid discharge valve and to generate different operating modes. It is shown that the excitation signals are persistently exciting of a certain order and cover the bandwidth of the system. In this study, the structure models (the output error model, the autoregressive with exogenous input model, the autoregressive moving-average with exogenous input model and the box Jenkins model) are identified for the increase mode and the decrease mode by employing the experimental data of a test automobile and using the ordinary least-squares method and the prediction error method. After validation of the model outcome by comparison with the experimental results, the best models are presented for the increase mode and the decrease mode of the hydraulic unit in a test automobile.
