This paper presents a method of computer support for teaching the Routh-Hurwitz criterion in two different undergraduate junior level Electrical Engineering courses at the United States Coast Guard Academy. Software Engineering (SWE) and Computer Control Systems (CCS) are two courses that students use C# programming and MATLAB® software to learn about the Routh-Hurwitz principle and its applications...
This paper presents a successful graphical technique for finding all discrete-time proportional integral derivative (PID) controllers that satisfy a robust stability constraint for heading control of a 2 meter autonomous sailing vessel. This problem is solved by finding all achievable discrete time PID controllers that simultaneously stabilize the closed-loop characteristic polynomial and satisfy...
Time delays in the feedback complicate the analysis and design of the closed-loop system. The use of a Smith predictor in combination with a Proportional Integral Derivative (PID) controller is a well-known technique for dealing with these delays in stable systems. However, many authors have questioned the robustness of this approach when the model of the plant is not known exactly. In this paper,...
This paper presents some of the successful design methodologies used to predict the robustness of a heading controller for a 2 meter autonomous sailing vessel. A graphical technique is introduced to estimate the discrete-time proportional integral derivative (PID) controller coefficients to satisfy H-infinity complementary sensitivity constraints for vessel control. We show that this problem can be...
In this paper, a unified approach is introduced for finding the stability boundary and the number of unstable poles in the integral derivative (ID) plane for continuous-time or discrete-time PID controllers. The ID plane is particularly important because in this plane it is easier than in the PI or PD planes to determine the entire stability region. These problems can be solved by finding all achievable...
This paper studied a new approach designed for a distributed wireless network under three adverse communication environment, such as, broadband noise jamming (BNJ), node geometry, and channel uncertainty. It is designed for a cooperative network consisting of one-source, one-destination and N-relay nodes that implement amplify-and-forward (AF) strategy. Deriving optimal relay amplifying matrix is...
This paper studies channel uncertainty and node geometry influences on a regenerative distributed decode-and-forward (DF) wireless relay network. A network consisting of one-source-one-destination pair and N-multibranch relay nodes without a direct link between the source and the destination is investigated. A new proposed detection scheme employs the maximum ratio combiner (MRC) principle. The new...
This paper introduces a cooperative distributed wireless relay network under a jamming environment at three different locations. An amplify-and-forward (AF) multiple-input single-output (MISO) system is considered with N-relay nodes. For full relay cooperation, all relay nodes in wireless relay networks exchange their received signals from source nodes with no errors. An optimal non-diagonal amplifying...
This paper presents a noncooperative distributed amplify-and-forward (AF) single-input multiple-output (SIMO) wireless relay networks under two adverse wireless communication environments: (1) node geometry and a jamming environment, and (2) channel uncertainty and a jamming environment. All relay nodes in wireless relay networks cannot exchange their received signals from source nodes for relay noncooperation...
In this paper a graphical method is introduced for finding all proportional integral derivative (PID) controllers that satisfy a robust performance constraint for a given single-input-single-output (SISO) linear time invariant (LTI) transfer function of any order with time-delay. This problem can be solved by finding all achievable PID controllers that simultaneously stabilize the closed-loop characteristic...
