ENGR 2900 students work on improving the SLICK Science cars that are used for an interactive summer camp for middle school students to learn more about engineering and robotics. This year, students plan to add a PID controller to the throttle so that the cars can maintain a desired speed regardless of the surface on which they are driving. PID controllers are a common way of aligning as closely as possible the output of a system to a desired value. The “P”, “I” and “D” in PID control stands for “proportional”, “integral” and “derivative”. Implementation of a PID control comes in comparing the output of a system (as read from a sensor) to a desired input. The difference between the two, the “error”, is then integrated and differentiated and the new output to the system is a scaled up or down version of the sum of the proportional, integral, and derivative terms. With the implementation of PID control, the motors on the SLICK Science cars will work harder to maintain a certain speed on rough terrain, such as grass, than they will on smooth surfaces like asphalt. The controller uses information from the GPS in a closed loop system in order to adjust power to the motors. PID controllers are a powerful way of controlling an input given a desired output and are used in many every day and industrial applications. This is a video of the presentation, "Using GPS to Implement PID Control for a Remote-Control Car’s Speed" given at the 2022 Undergraduate Projects & Research Conference at Salt Lake Community College.
