Hybrid Intelligent Method for Recognition of Common Types of Control Chart Patterns

Abstract: Automatic recognition of abnormal patterns in control charts has seen increasing demands nowadays in manufacturing processes. This paper presents a novel hybrid intelligent method (HIM) for recognition of the common types of control chart pattern (CCP). The proposed method includes two main modules: a clustering module and a classifier module. In the clustering module, the […]

Stabilization-of-Linear-Time-Invariant-Fractional-Order-Switched-Systems

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 […]

The Challenges of Attracting Millennials to Industrial Careers

There has been considerable discussion of late about the mass retirements of baby boomers from the industrial workforce and the lack of appropriate talent to fill the gap. Many baby boomers believe that the younger generation—the millennial generation—is not up to the task and that young people have no interest in taking on the challenges. […]

Modified Smith Predictor-Based Cascade Control of Unstable Time Delay Processes

  Abstract: An improved cascade control structure with a modified Smith predictor is proposed for controlling open-loop unstable time delay processes. The proposed structure has three controllers of which one is meant for servo response and the other two are for regulatory responses. An analytical design method is derived for the two disturbance rejection controllers by […]

How to Improve Industrial Productivity with Loop Calibration

The typical approach to calibration has been to regularly test instrumentation that affects successful control, safe operation, quality, or other relevant criteria. In most cases, scheduling is conservative, and methods at a particular site have evolved over time. Instrument technicians follow practices that were set up many years ago. It is not uncommon to hear, […]

Simulation and Stability Analysis of Neural Network Based Control Scheme for Switched Linear Systems

Abstract: This paper proposes a new adaptive neural network based control scheme for switched linear systems with parametric uncertainty and external disturbance. A key feature of this scheme is that the prior information of the possible upper bound of the uncertainty is not required. A feedforward neural network is employed to learn this upper bound. The […]

What Is the Next Generation of Process Automation Wireless Technology?

Wireless technology is an essential business enabler for the automation world. It has gained rapid acceptance in many industrial sectors because of its cost effectiveness, reliability, fast deployment, and flexibility. Over the past four decades, ultrahigh frequency (UHF) radios have been widely used for long-range supervisory control and data acquisition (SCADA) connectivity in the oil […]
