Abstract

This paper presents a simulation device for infrared stealth spherical target and a feedforward temperature compensation algorithm for its surface temperature. A three-dimensional model and a mathematical model based on heat transfer equation are established. Experimental data from three different spherical targets is used to calculate feedforward compensation and obtain a detailed control law. Experiments verify the reliability of the mathematical model and the accuracy of the temperature control algorithm. The algorithm can control the surface temperature of the spherical target within ±2 °C and has good system dynamic characteristics.
