2015 journal article

A non-uniform multi-rate control strategy for a Markov chain-driven Networked Control System

Information Sciences, 321, 31–47.

By: Á. Cuenca  n, U. Ojha*, J. Salt * & M. Chow*

author keywords: Networked Control System; Unmanned ground vehicle; Network delay; Packet disorder; Multi-rate control system; PID controller
topics (OpenAlex): Stability and Control of Uncertain Systems; Mobile Ad Hoc Networks; Distributed Control Multi-Agent Systems
TL;DR: A non-uniform multi-rate control strategy is applied to a kind of Networked Control System (NCS) where a wireless path tracking control for an Unmanned Ground Vehicle (UGV) is carried out to face time-varying network-induced delays and to avoid packet disorder. (via Semantic Scholar)

2012 article

Gene library for real-time monitoring of large scale time-sensitive systems

Ojha, U., Asr, N. N. R., & Chow, M.-Y. (2012, May 1).

By: U. Ojha n, N. Asr n & M. Chow n

topics (OpenAlex): Artificial Immune Systems Applications; Gene Regulatory Network Analysis; Real-time simulation and control systems
TL;DR: A gene library was created that eliminated the need to perform heavy computations (solving second order differential equation) while still maintaining the accuracy of prediction to +/- 4% of the actual value in the normal operating range. (via Semantic Scholar)

2011 article

Gene libraries for a next generation warning system in Intelligent Transportation

Ojha, U., & Chow, M.-Y. (2011, November 1).

By: U. Ojha n & M. Chow n

topics (OpenAlex): Advanced Chemical Sensor Technologies; Gene expression and cancer classification; Evolutionary Algorithms and Applications
TL;DR: It is shown that gene libraries are capable of reducing the complexity of the problem by storing only the relevant information and a formulation for next generation warning system within the framework of gene libraries is proposed and simulations are presented that compare this approach with fuzzy inference system.

Predictive constrained gain scheduling for UGV path tracking in a networked control system

Klingenberg, B. R., Ojha, U., & Chow, M.-Y. (2009, October 1).

By: B. Klingenberg n, U. Ojha n & M. Chow n

topics (OpenAlex): Control and Dynamics of Mobile Robots; Vehicle Dynamics and Control Systems; Traffic control and management
TL;DR: This paper presents a predictive gain scheduler for path tracking control in a networked control system with variable delay that uses path specific characteristics to evaluate the effectiveness of each generated control signal. (via Semantic Scholar)
