<p>Redundant controllers are being designed to provide improved system reliability to meet the needs of various applications. In some implementations of these systems unacceptable system transients have occured when a single-controller failure occurs. The problem has been treated using case-by-case correction which is not sufficiently general in application to meet the needs of systems which may be user-programmed. Redundant control systems generalized as ideal and nonideal using two specific voting schemes are examined to gain insight into theoretical characterization of their performance under single-point failure modes and the limitations of applicability for the characterizations. State-model computer simulation is used to demonstrate the characterizations. A suggested direction for a general solution to the problem based on the chatacterizations is described.</p> / Master of Science

The advent of the VLSI technology makes it feasible to offer a once expensive system attribute called fault-tolerance to a wide variety of applications. This can be accomplished by using off-the-shelf single board computers and peripherals as the heart of the system. Custom design boards can then be added to meet the specific requirements of each application.

An algorithm to design simple gain scheduled nonlinear PID controllers for nonlinear plants is investigated. Design information is obtained from measurements of the nonlinear plant about selected equilibrium points. Simulations are performed on two different nonlinear CSTR models. The first simulation produced an unexpected result: that linear output feedback performed better than state feedback for the particular model. The second simulation showed that the nonlinear PID controller performed as well as a complex nonlinear controller. A literature search for similar nonlinear controllers concluded that the nonlinear PID controller presented in this thesis did not provide a unified framework for previous work. / Master of Science
