Approximate controller design for singularly perturbed aircraft
Graziosi, Joseph E. (Wichita State University, 2014-05)The purpose of this thesis was to extend the quasi-steady-state approximation and matrix block diagonalization methods utilized in the work of Shim and Sawan [1]. These authors showed that an approximate controller solution ... -
A bridge from stability to robust performance design of PID controllers in the frequency domain
Emami, Tooran (Wichita State University, 2009-12)A graphical technique for finding proportional integral derivative (PID) controllers that stabilize a given single-input-single-output (SISO) linear time-invariant (LTI) system of any order system with time-delay has ... -
Decentralized control of interconnected singularly perturbed systems
Alfuhaid, Walid Sulaiman (Wichita State University, 2016-08)Designing a controller for large scale systems usually involve a high degree of complexity and computation ability. When talking about decentralized interconnected systems, the complexity and computation are not the only ... -
Face recognition with Gabor phase
Venkata, Anjaneya Subha Chaitanya Konduri (Wichita State University, 2009-07)Face recognition is an attractive biometric measure due to its capacity to recognize individuals without their cooperation. This thesis proposes a method to dynamically recognize a facial image with the help of its valid ... -

Manduva, Prithvi (Wichita State University, 2014-05)The Internet, which has had an impact on almost every facet of our lives. It has grown at a rapid pace and devices connecting to in direct proportion, in turn increasing the routing tables. The Location Identifier Separation ... -
Mapping controllers from the s-domain to the z-domain using magnitude invariance and phase invariance methods.
Vadhavkar, Prathamesh R. (Wichita State University, 2007-12)Design by emulation has been widely used in the field of control systems. Design by emulation is a process where initially a continuous time controller is designed to achieve desired closed loop specifications. This ... -
Openflow based traffic engineering for mobile devices
Hirannaiah, Radhika M. (Wichita State University, 2014-07)Expansion in mobile devices has led to rapid growth in data traffic. Currently, networks are complex and difficult to manage. The exponential increase in audio/video streaming and continuous demand for network connectivity ... -
Proportional-Integral-Derivative (PID) controller design for robust stability of arbitrary order plants with time-delay and additive uncertainty
Gogoi, Manoj (Wichita State University, 2010-08)In the process control industry, majority of control loops are based on Proportional-Integral-Derivative (PID) controllers. The basic structure of the PID controllers makes it easy to regulate the process output. Design ... -
Robust and reduced order h-infinity filtering via LMI approach and its application to fault detection
Kim, Young-Man (2006-05)The objective of this dissertation is to develop a practical methodology for designing full and reduced order H[infinity] filter for plants with polytopic model uncertainty. Because the polytopic model description is convex, ... -
Robust PID control using a Smith predictor for time delay systems
Veeramachaneni, Siva Rama Krishna (Wichita State University, 2013-12)Time delays are unavoidable in many mechanical and electrical systems. The presence of delay typically imposes strict limitations on achievable feedback performance in both continuous and discrete systems. The presence of ... -
Single network adaptive critic aided nonlinear dynamic inversion
Lakshmikanth, Geethalakshmi S. (Wichita State University, 2012-05)Approximate Dynamic Programming (ADP) offers a systematic method of optimal control design for nonlinear systems. Of the many architectures based on ADP, Adaptive Critic (AC) is the most popular. An AC consists of two ... -
Stabilization of an arbitrary order transfer function with time delay using PI, PD and PID controllers
Sujoldžić, Sead (2005-12)This thesis is concerned with developing a procedure for stabilizing a linear time-invariant plant of an arbitrary order with time delay utilizing proportional-integral (PI), proportional-derivative (PD) and proportional ... -
