A frequency compensation algorithm of four-wheel coherence random road
(Journal article; Peer reviewed, 2013)The road surface roughness is the main source of kinematic excitation of a moving vehicle, which has an important influence on vehicle performance. In recent decades, random road models have been widely studied, and a ... -
Application of learning pallets for real-time scheduling by use of artificial neural network
(Chapter; Peer reviewed, 2011)Generally, this paper deals with the problem of autonomy in logistics. Specifically here, a complex problem in inbound logistics is considered as real-time scheduling in a stochastic shop floor problem. Recently, in order ... -
H∞ fuzzy control of DC-DC converters with input constraint
(Journal article; Peer reviewed, 2012)This paper proposes a method for designing H∞ fuzzy control of DC-DC converters under actuator saturation. Because linear control design methods do not take into account the nonlinearity of the system, a T-S fuzzy model ... -
Improving performance of evolutionary algorithms with application to fuzzy control of truck backer-upper system
(Journal article; Peer reviewed, 2013)We propose a method to improve the performance of evolutionary algorithms (EA). The proposed approach defines operators which can modify the performance of EA, including Levy distribution function as a strategy parameters ... -
Input-to-state stability of Lur'e hyperbolic distributed complex-valued Parameter control systems: LOI approach
(Journal article; Peer reviewed, 2013)In this work, input-to-state stability of Lur'e hyperbolic distributed complex-valued parameter control systems has been addressed. Using comparison principle, delay-dependent sufficient conditions for the input-to-state ... -
Mathematical modeling and parameters estimation of a car crash using data-based regressive model approach
(Journal article; Peer reviewed, 2011)n this paper we present the application of regressive models to simulation of car-to-pole impacts. Three models were investigated: RARMAX, ARMAX and AR. Their suitability to estimate physical system parameters as well as ... -
Modeling and backstepping control of the electronic throttle system
(Journal article; Peer reviewed, 2013)Electronic throttle is widely used in modern automotive engines. An electronic throttle system regulates the throttle plate angle by using a DC servo motor to adjust the inlet airflow rate of an internal combustion engine. ... -
Normal pressures and frictional tractions on shallow conical hopper walls after concentric filling: Predictions and experiments
(Journal article; Peer reviewed, 2013)A silo with a shallow hopper is designed to achieve the required silo capacity when the headroom available is limited, provided that the issue of segregation of stored particulate solids is not a problem. Several analytical ... -
Observer-based robust control for hydraulic velocity control system
(Journal article; Peer reviewed, 2013)This paper investigates the problems of robust stabilization and robust control for the secondary component speed control system with parameters uncertainty and load disturbance. The aim is to enhance the control performance ... -
Peak power demand and energy consumption reduction strategies for trains under moving block signalling system
(Journal article; Peer reviewed, 2013)In the moving block signalling (MBS) system where the tracking target point of the following train is moving forward with its leading train, overload of the substations occurs when a dense queue of trains starts (or restarts) ... -
Robust delay-dependent H∞ control of uncertain time-delay systems with mixed neutral, discrete, and distributed time-delays and Markovian switching parameters
(Journal article; Peer reviewed, 2011)The problem of robust mode-dependent delayed state feedback H ∞ control is investigated for a class of uncertain time-delay systems with Markovian switching parameters and mixed discrete, neutral, and distributed delays. ... -
Robust reliable control of uncertain discrete impulsive switched systems with state delays
(Journal article; Peer reviewed, 2013)This paper is concerned with the problem of robust reliable control for a class of uncertain discrete impulsive switched systems with state delays, where the actuators are subjected to failures. The parameter uncertainties ... -
Signal analysis and performance evaluation of a vehicle crash test with a fixed safety barrier based on Haar wavelets
(Journal article; Peer reviewed, 2011)This paper deals with the wavelet-based performance analysis of the safety barrier for use in a full-scale test. The test involves a vehicle, a Ford Fiesta, which strikes the safety barrier at a prescribed angle and speed. ... -
Stability analysis and stabilization of T-S fuzzy delta operator systems with time-varying delay via an input-output approach
(Journal article; Peer reviewed, 2013)The stability analysis and stabilization of Takagi-Sugeno (T-S) fuzzy delta operator systems with time-varying delay are investigated via an input-output approach. A model transformation method is employed to approximate ... -
The identification of convex function on riemannian manifold
(Journal article; Peer reviewed, 2014)The necessary and sufficient condition of convex function is significant in nonlinear convex programming. This paper presents the identification of convex function on Riemannian manifold by use of Penot generalized directional ... -
The impact of the subsidy policy on total factor productivity : an empirical analysis of China's cotton production
(Journal article; Peer reviewed, 2013)This paper develops one model to explore the relationship between the subsidy policy and the agricultural total factor productivity (TFP). It indicates that the agricultural TFP will be lower after the subsidy policy is ... -
Using metaheuristic and fuzzy system for the optimization of material pull in a push-pull flow logistics network
(Journal article; Peer reviewed, 2013)Alternative material flow strategies in logistics networks have crucial influences on the overall performance of the networks. Material flows can follow push, pull, or hybrid systems. To get the advantages of both push and ...
