The Fuzzy Inference System Translator (FIST) and Micro-Controller Regulation of Plant Growth Chamber Temperature and Humidity 981677
The Fuzzy Inference System Translator (FIST) is a tool in the realization of standalone, fully-programmable, fuzzy logic micro-controllers for the regulation of advanced life support system temperature and humidity subsystems. Analog input signals may include chamber temperature, relative humidity, CO2 concentration and nutrient level. Analog output signals can be, for example, heater voltage and condensing heat-exchanger cold-water valve voltage, nutrient pump actuator voltage and grow-lamp actuator voltage. Features of the micro-controller described, include keypad entry of sensor calibration data and online modification of the photo-period, temperature, humidity and CO2 levels during full system operation. All system inputs and outputs can be selected for read-out on a liquid crystal display (LCD).
