A better understanding of closed-loop control, and how to tune it, can be found by looking at the individual parts of the PID equation and the effect of each on the controlled output By Bill Dehner ...

Well designed conventional PID controllers using Ziegler-Nichols method are having large overshoot and settling time. Significant research work has been carried out to improve the performance of ...

Though pretty complex in nature and difficult to program, there are way more benefits to tuning and using PID loops that can ultimately be incredibly useful when it comes to your development process.
