A Gentle Introduction To Learning Calculus. I have a love/hate relationship with calculus: it demonstrates the beauty of math and the agony of math education. Calculus relates topics in an elegant, brain-bending manner. My closest analogy is Darwin’s Theory of Evolution: once understood, you start seeing Nature in terms of survival. You understand why drugs lead to resistant germs (survival of the fittest). You know why sugar and fat taste sweet (encourage consumption of high-calorie foods in times of scarcity). It all fits together. Calculus is similarly enlightening. They are. Unfortunately, calculus can epitomize what’s wrong with math education.
It really shouldn’t be this way. Math, art, and ideas I’ve learned something from school: Math isn’t the hard part of math; motivation is. Teachers focused more on publishing/perishing than teachingSelf-fulfilling prophecies that math is difficult, boring, unpopular or “not your subject”Textbooks and curriculums more concerned with profits and test results than insight Poetry is similar.

Adjusting PID loop gains can remove overshoots, decrease settling time, and enhance stability in machines of all types. By: Kristin Lewotsky, Contributing Editor (posted 05/11/2011) Servo motors provide precise, accurate, repeatable motion, courtesy of closed-loop feedback. Motion control is a systems-level solution, however. No matter how high quality the motors and feedback, if the system hasn't been tuned to produce the best possible motion for the application, even the best components will underperform. One of the most common approaches to servo control and tuning is the proportional, integral, derivative (PID) loop method. Consider a single-axis motion system. In this best case scenario, the system arrives at xc within one or two iterations.
One way to express the output of the PID loop is as follows: where Kp is the proportional term, Ki is the integral term, and Kd is the derivative term. The integral gain tends to act primarily on the low-frequency components of machine response.
