Experimental research on muffle furnace dynamic properties

Purpose. To develop the method and software for building empirical models of muffle furnaces with two heating elements. Methodology. The processing experimental data according to improved algorithm, which is based on areas method, used constructing furnace. Experimental research furnace dynamic conducted using following methodology. cooled room temperature then lower heater turned temperatures at output are fixed two-channel controller MIC-344. second cycle began by cooling turning upper heater. Observations results experiment until stabilized outputs Archiving trends carried out RS485/Ethernet interface SmartReview (a product private limited company “Microl”). Findings. developed can be iteratively selection optimal model criterion root mean square deviation calculated data. calculating acceleration curve transfer functions coefficients a variable discreteness step in order compare modeling results. Twelve were tested four signal transmission channels process research. It has been established that only them stable (have left-hand roots characteristic equation). Among selected sustainable models, numerator polynomial equaled denominator three as best (according criterion). A structural diagram created synthesized furnace, includes cross connections. Originality. For first time, electrical energy sources developed, describes its properties object automatic control high accuracy, enables reveal presence internal cross-connections, significantly complicate controlling object. Practical value. electric (tens) synthesis high-precision system
