Adaptive Control of Systems with Actuator and Sensor Nonlinearities

by Gang Tao, Petar V. Kokotovic

Overview

An in-depth examination of intelligent approaches to increasing the accuracy of a variety of system components. Utilizing a unified, adaptive, inverse approach, the book offers electrical, mechanical, chemical, aeronautical and computer engineers methods for controlling many of the "hard" nonlinearities of frequently-employed control systems such as dead-zone, backlash and hysteresis. Discusses such nonlinearities at both the input and output points of a linear part and within both continuous time designs and discrete time designs.

Editorial Reviews

Introduces a unified adaptive inverse approach for controlling systems with unknown nonlinearities, thus dealing with stubborn engineering problems posed by imperfections of actuators and sensors. Shows how to counteract the effects of dead-zone, backlash, hysteresis, and other nonlinearities with real-time computations that avoid the need for expensive specialized hardware. The examples range from satellite antennas to consumer electronics. Addressed to engineers, researchers, and graduate students. Annotation c. Book News, Inc., Portland, OR (booknews.com)
