<p style="color: grey"> Python recipe 577231 by <a href="/recipes/users/4114638/">Caner</a> (<a href="/recipes/tags/controller/">controller</a>, <a href="/recipes/tags/derivative/">derivative</a>, <a href="/recipes/tags/discrete/">discrete</a>, <a href="/recipes/tags/integral/">integral</a>, <a href="/recipes/tags/pid/">pid</a>, <a href="/recipes/tags/proportional/">proportional</a>, <a href="/recipes/tags/python/">python</a>). </p> <p>The recipe gives simple implementation of a Discrete Proportional-Integral-Derivative (PID) controller. PID controller gives output value for error between desired reference input and measurement feedback to minimize error value.
