Let's MAT, people!
AI Fuzzy Logic PID temperature control technology
MAT concept, approach, and treatment methodology were developed by paintings conservators Nina Olsson and Tomas Markevicius, who have been using precision heat transfer in their treatments since 2003. For more details see publications.
MAT is an acronym for Mobile Multipurpose Accurate Thermal management system for heritage conservation applications. The system is powered by a small and lightweight portable precision Mat-lab console (1500W/125 VAC or 1985W/230 VAC) regulated with a Fuzzy Logic AI PID temperature controller. A PID stands for the proportional–integral–derivative controller, which employs a control loop mechanism to continuously calculate an error value as the difference between the desired set point (SP) temperature and a measured process variable (PV) and applies a correction based on proportional, integral, and derivative terms (denoted P, I, and D). Moreover, MAT-lab uses AI Fuzzy Logic control technology, which provides an optimized approach to dealing with imprecision in complex situations. Fuzzy logic AI is self-training, it studies the heat transfer patterns and applies corrections for the future. In the other words, the more Mat-lab is used (trained), the more accurately it works. The feedback is acquired using a T-type thermocouple (sensor), which provides optimal accuracy within the temperature range used by conservators. MAT-lab measures the surface temperature 20 times/second and the PID algorithm constantly corrects the energy flux to the mat providing an accurate and homogenous heat transfer in the low-energy range.
The MAT-lab power console (7.39 x 4.75 x 3.21” / 18.71 x 11.38 x 8.15 cm) is connected to flexible silicone heat transfer mats of various sizes and an external thermocouple sensor. The operational temperature range is from room temperature to the customary heat activation temperatures (21-65ºC / 70-150ºF). The display may be set in Celsius or Fahrenheit. The console has a programmed safety upper limit of 70ºC / 158ºF. The console can be used only with the authentic Precision Mat mats, which are calibrated to the console. Any other third-party mats should not be used in any circumstances. A MAT starter kit includes a MAT-lab console, a temperature sensor (T-type thermocouple), and one A4 size silicone rubber heater. Additional mats of standard sizes listed below are available. The MAT-lab EU console can power mats from very small sizes up to 76 x 102 cm/ 30" x 40". Custom shapes and sizes, including extra-large mats, may be designed for your specific needs. Larger mats will require customization of both the mat and the console to provide adequate power and may require voltage at 240VAC or higher. However, in the actual conservation treatments, 99% of studio needs could be met by using the standardized sizes, which we selected based on our experience using mats since 2003.
