SY311 · Temperature Control Module

Continuous and discontinuous temperature control experiments

Experiments
  • Investigation of continuous closed-loop temperature control
  • Study of discontinuous (on/off) temperature control systems
  • PID parameter tuning for optimal temperature stability
  • Effect of disturbance variables (fan speed, throttle position)
  • Measurement of dead time and time constants in thermal systems
  • Comparison of proportional, PI, PD, and PID control strategies
  • Real-time temperature monitoring and trend analysis
SY311
Description
    The SY311 is a compact thermal control module designed for hands-on study of continuous and discontinuous feedback control loops. It features a unipolar electric heater with integrated temperature sensor and fan motor, housed in a transparent air channel for direct visual observation of the heating process. The module is equipped with dual integrated power amplifiers enabling multi-input control strategies such as Fuzzy logic control. Two built-in disturbance mechanisms allow realistic exploration of process perturbations.
