Ellis teaches engineers how to use the computer to design and troubleshoot a basic control system and uses Spice, a popular circuit simulation program, applied to control systems. Background material and mathematical development are kept to a minimum. Note: an evaluation version of PSpice is available free from MicroSim Corporation; the programs and models in the book can be obtained free from the author on a diskette for the PC and compatibles.
