This paper introduces interactive animations as a support resource for learning concepts of control systems. The animations are focused on three dynamic systems: a tank, a spring-damping-mass system and a roller-plane. The user can adjust the parameters and input variables, and observe the output variable behavior. The animations offer a learning environment, which allows students develop different activities to learn basic control concepts like Feedback, Modeling, time and frequency domain Analysis, Stability and Compensation without a detailed mathematical explanation. The animations propose an active learning environment through playing that engages students in the subject. The animations are developed by using Easy Java Simulations.
