Van de Vegte, Feedback Control Systems, Prentice-Hall (has some Matlab examples).

Ogata, System Dynamics, Prentice-Hall.

DiStefano, Feedback and Control Systems, Schaum.

D'Azzo & Houpis, Feedback Control System Analysis & Synthesis, McGraw-Hill (this is an old book).

Shinskey, Process Control Systems (this is my wife's, i haven't used it).

Ogunnaike & Ray, Process Dynamics, Modelling, and Control, Oxford (this is my wife's also).

Houpis & Lamont, Digital Control Systems, McGraw-Hill.

also, Gnu (www.gnu.org) has a free Matlab analogue,
Octave, which i haven't used, and a plotting package Gnuplot, which i have used (but not for a while), and the Gnu plotting utilities, which i just found while searching www.gnu.org (from the Gnuplot site it looks like there is no relation between Gnuplot and the Gnu Plotting Utilities). you can build gnuplot under linux, ms-windows, ms-dos, etc.
