## Heat Transfer Dynamics and Control

This lab is an application of feedback control for a temperature control device. There are two heaters and two temperature sensors. The heater power output is adjusted to maintain a desired temperature setpoint. Thermal energy from the heater is transferred by conduction, convection, and radiation to the temperature sensor. Heat is also transferred away from the device to the surroundings. This lab is a resource for model identification and controller development. It is a pocket-sized lab with the purpose of reinforcing control theory for students.

Portable Temperature Control Lab for Learning Process Control

This lab teaches principles of system dynamics and control. In particular, this lab reinforces:

Instructor and Development Resources

#### Lab Instructions

The following activities should be completed with this lab.

A report is due at the end of the project that details the modeling, parameter estimation, and control performance.

Students are assembled into groups of two for this lab. One report should be submitted for each group.

#### Tutorial Videos (MATLAB/Simulink and Python)

Solutions include additional advanced methods for control that are not covered in this class but are learned in Dynamic Optimization.

• Dynamic modeling
• First principles
• Empirical / machine learning
• Dynamic Estimation
• Parameter regression
• Kalman filter
• Moving Horizon Estimation
• Process control
• ON/OFF control
• PID control
• Stability analysis
We give the small and inexpensive process control experiment to students to reinforce concepts in dynamics and control theory. A few other universities are currently adopting this lab for process control instruction. Current participating universities include Notre Dame, Iowa State, Oklahoma State, and Christian Brothers University. This lab was presented at the 2017 ASEE Summer School at NCSU as part of resources for teaching process transient analysis. Lab solutions for instructors are provided in Python and MATLAB. Instructors can join a bulk order by filling out an information form. The lab is also available for purchase from the PayPal link below. A first version of the lab at BYU was $49 each as shown in the parts list but is now reduced due to bulk suppliers. The lab kit includes: • Arduino Uno • Temperature control PCB shield • USB barrel jack power cable for heaters • 5V USB power supply (US plug) • USB cable for serial connection to MacOS, Windows, or Linux computer • Small cardboard box Cost:$20 USD/lab + shipping
