Dealing with a control system that is a second order system adds certain complexities compared to a first order system. In this video tutorial, we learn about the mathematical form of second order systems and we briefly review how to get the transfer function for the system. We then discuss undamped, underdamped, critically damped, and over-damped systems while using some animated mechanical examples and an RLC electrical circuit to understand these concepts. Finally, using LTSpice, we model an RLC circuit with varying damping ratios and see what the actual output is like. We are definitely getting into the good stuff with control systems!
This video tutorial is based on the excellent written tutorial that Kushal created and we highly recommend you go check it out to get to more in-depth information and a more rigorously mathematical approach. His tutorial is found here:
