DIGITAL EQUIPMENT FOR THE TEMPERATURE CONTROL INSIDE AN ENCLOSURE. THE SYSTEM MODELING
Journal Title: ANALELE UNIVERSITATII DIN CRAIOVA - Seria Inginerie electrica - Year 2010, Vol 34, Issue 34
Abstract
The fast design flow for the temperature control inside a thermal enclosure includes some identification elements, modeling and simulations for the digital control algorithms in different forms and a preparation of the real-time algorithm using an appropriate programming language for the hardware implementation. The solution, after this short but holistic approach, is a ready to use form for the computing relations associated to the control algorithm and the optimum values for the tuning parameters. In this stage, many hardware options and constraints must be considered so that the models and simulations could reproduce the real operating conditions of the experimental platform (that will be presented in a subsequent paper). For a small thermal enclosure designed and realized both for educational and scientific purposes, the first step is to identify a transfer function based on IN / OUT experimental data. Using this result, several models were analyzed, considering different external conditions, various operation modes and several control algorithms: by commutation (On / Off, with hysteresis band), proportional (P), PI (continuous and digital forms). A careful design of the models was tuned so that all the basic processing for the simulations should as closed as possible with the realtime operation of a target microcontroller, with its specific hardware / software constraints.
