摘要:University control engineering courses usually focus on Proportional Integral Derivative (PID) controllers. Moreover PID controllers are used in more than 90% of the industrial control applications, because they are relatively cheap, easy to use, and robust enough for most industrial applications. However, university teaching attaches most importance to the theoretical knowledge of PID controllers, rather than the practical skills required to support the use of these controllers in industry. In addition, the cost and space challenges associated with hands on laboratories make simulation based laboratories a more attractive option for teaching PID controllers. Unfortunately, simulations do not capture the complexity of control systems that are important to develop the practical skills of students. In this paper, we present a laboratory setup that is used to teach practical skills in PID tuning. The system controls the temperature of a small fictitious house whose temperature is affected by an uncontrolled heating source and blow fan. The PID data is accessible to the system user through OLE( Object Linking & Embedding) for Process Control, also referred as Open Process Control(OPC) technology. This technology allows the system to be used as a hands-on or remote laboratory, which allows students to learn the complexity of PID controllers, while removing the time and space constraints imposed by purely hands on laboratories. Being accessible remotely, the setup enables and encourages instructors to include demonstrations of PID tuning into their lectures
