说明：  这是个混沌理论应用中的李雅普诺夫指数源代码，里面的方程是著名的lorenze方程，它可以帮助我们分析混沌的动力学特性，希望对大家有用(This is application of chaos theory in the Lyapunov index of the source code, which the equation is the famous lorenze equation, it can help us analyze chaotic dynamics, we hope to be useful)

The PID controller is the most widely used controller in industrial systems. However, appropriately tuning a PID controller is not an easy task although it has only three parameters at most. This submission provides a tool for beginners to learn PID tuning.
