Pid controller for thermal control in satellites

Abstract

The paper gives the application of PID controller in satellite launching; it gives out the different technique which involves PID controller. It involves the temperature control (thermistor) in heater which is situated in the satellite. PID controller is implemented with the use of programmable logic controller. Using Ordinary control techniques, it is very difficult for controlling temperature; hence the purpose of proposed research is implementing PID controller design using programmable logic controller (PLC) in order to control the temperature and maintain the output in such a way that there is zero error between process variable and set point/desired output by closed loop operations in the satellite by avoiding the manual monitoring system. A thorough analysis using various PID parameters is presented in terms of system response. Performance of the controller is examined in terms of duty cycle, average current and power dissipation. Finally, a comparative analysis of PID controller for thermal control in satellite is presented.
