Java-based simulator of dynamical systems and PID control

In this paper, a java-based simulator of Dynamical Systems and PID control is presented. This simulator implements linear low-order process models (first order, second order and third order), open-loop architecture and closed-loop architecture with a linear PID feedback controller. At the past, a hardware simulator (HW123b) for the three process models was developed in our group, and now the equivalent software version is presented. Modeling and dynamical simulation are now basic tools for understanding and verifying theoretical subjects. The main contribution is a Java application that can be used by the instructor / user in a blended learning environment to teach / learn the basic notions of dynamical systems behavior and also the effect of PID feedback controllers in the closed-loop system.
