Richard Phelan discovered a fundamental improvement in practical control systems. Slowly, it's changing the world. Largely perhaps because the idea is so, well, obvious, Professor Phelan became an enthusiast, who quite reasonably, dismissed traditional Proportional + Integral + Derivative (PID) algorithms and all the Laplace transforms that go with them. He calls his idea (his discovery) Pseudo Derivative Feedback (PDF). In this book, he shows you how to provide for parallel proportional feedback signals downstream of the integrator; these signals serve the function of differentiated feedback signals without the noise and overshoot associated with PID controllers. It's elegant. It will allow you to do more with less.
