  This document describes the design of a PID controller for a rotation pitch
plant of a degree freedom. In the controller design, the tuning methods of
Astr\"on H\"agglund (AH), Kaiser Chaira (KC) and Kaiser Rajka (KR) will be
used, verifying the performance in simulations and in the plant. Finally, the
development for the implementation of an analog PID controller through circuits
with operational amplifiers is described.
