Issues in the implementation of automotive control systems.

Abstract

This thesis presents enhancements to the design, synthesis, and implementation phases of the automotive control system development process. The torque converter slip control problem is presented and used as an application for the theoretical developments. These developments include modifications to the limits of performance analysis used in design phase feasibility studies. For the synthesis and implementation phases, a lifted-$\delta$-operator representation for discrete-time-multi-rate systems is developed. It is shown that this lifted-$\delta$-operator representation can be used to approximate single and multi-rate hybrid systems. It is also shown, via example, that $\delta$-operator representations can reduce coefficient and variable wordlength requirements when fixed-point arithmetic is employed.
