How to Reduce Diesel Engine Pollution Through a High-Pressure Common Rail Injection System

Abstract: In this paper, modeling and common-rail pressure control of high-pressure common rail injection system (HPCRIS) is presented. The proposed mathematical model of high pressure common rail injection system which contains three sub-systems: high pressure pump sub-model, common rail sub-model and injector sub-model is a relative complicated nonlinear system. The mathematical model is validated by the […]

Dual-Mode Adaptive Fractional Order PID Controller with Feedforward Controller for Quadruple Tank Process

Abstract: The quadruple tank process (QTP) is a well-known benchmark of a nonlinear coupled complex MIMO process having both minimum and nonminimum phase characteristics. This paper presents a novel self tuning-type dual-mode adaptive fractional order PID controller along with an adaptive feedforward controller for the QTP. The controllers are designed based on a novel variable parameter […]

Optimal PID Controller for Standard Second-Order Plus Time Delay Systems

Abstract: An improved tuning methodology of PID controller for standard second order plus time delay systems (SOPTD) is developed using the approach of Linear Quadratic Regulator (LQR) and pole placement technique to obtain the desired performance measures. The pole placement method together with LQR is ingeniously used for SOPTD systems where the time delay part is […]

PWM-Switching Pattern-Based Diagnosis Scheme for Induction Motor Drives

Abstract: This paper deals with a fault detection technique for insulated-gate bipolar transistors (IGBTs) open-circuit faults in voltage source inverter (VSI)-fed induction motor drives. The novelty of this idea consists in analyzing the pulse-width modulation (PWM) switching signals and the line-to-line voltage levels during the switching times, under both healthy and faulty operating conditions. The proposed […]

Applications of Thermoelectric Modules on Heat Flow Detection

Abstract: This paper presents quantitative analysis and practical scenarios of implementation of the thermoelectric module for heat flow detection. Mathematical models of the thermoelectric effects are derived to describe the heat flow from/to the detected media. It is observed that the amount of the heat flow through the thermoelectric module proportionally induces the conduction heat owing […]

Fault-Tolerant-Synchronization-of-Chaotic-Gyroscope-Systems

Fault Tolerant Synchronization of Chaotic Heavy Symmetric Gyroscope Systems

Abstract: In this paper, fault tolerant synchronization of chaotic gyroscope systems versus external disturbances via Lyapunov rule-based fuzzy control is investigated. Taking the general nature of faults in the slave system into account, a new synchronization scheme, namely, fault tolerant synchronization, is proposed, by which the synchronization can be achieved no matter whether the faults and […]

Stabilization of Linear Time Invariant Fractional Order Switched Systems

Abstract: This paper presents the stabilization problem of a linear time invariant fractional order (LTI-FO) switched system with order 1<q<21<q<2 by a single Lyapunov function whose derivative is negative and bounded by a quadratic function within the activation regions of each subsystem. The switching law is extracted based on the variable structure control with a sliding […]

An Efficient Decentralized Iterative Learning Tracker

Abstract: In this paper, an efficient decentralized iterative learning tracker is proposed to improve the dynamic performance of the unknown controllable and observable sampled-data interconnected large-scale state-delay system, which consists of NN multi-input multi-output (MIMO) subsystems, with the closed-loop decoupling property. The off-line observer/Kalman filter identification (OKID) method is used to obtain the decentralized linear models […]

Bilateral Control of Master-Slave Manipulators with Constant Time Delay

  Abstract: This paper presents a novel teleoperation controller for a nonlinear master-slave robotic system with constant time delay in communication channel. The proposed controller enables the teleoperation system to compensate human and environmental disturbances, while achieving master and slave position coordination in both free motion and contact situation. The current work basically extends the passivity […]
