TcuTemperature control unitIt is used in various industries such as chemical and pharmaceutical industries when reaction kettle control is required. The multi reactor refrigeration, heating, and temperature control system is abbreviated asTCUSo, thenTcuHow does the temperature control unit operate?TcuHow does the principle of temperature control unit come about?

　　Change control settings

Multi reactor refrigeration, heating, and temperature control systemTCUThe temperature control unit can quickly respond to system lag and achieve small system overshoot by changing the control setting value. Control by two groupsPID(Each group)PIDThe two sets of control loops are called the main loop and the slave loop, and the control output of the main loop serves as the set value of the slave loop.

　　TcuTemperature control unitThe system adopts feedforward when setting upPVThe main control circuitPIDOutput of operation results and feedforwardPVAfter the signal is combined, it is used as the set value of the control loop to control the temperature gradient and ensure the temperature control accuracy of the system. (General anti lag series control)

　　Specially designed hysteresis estimator as feedback signal

Specially designed lag estimator (model free self built tree algorithm) generates substitute process variablesy（t）The dynamic signalyc（t）As a feedback signal. rightTcuThe temperature control unit generates ae（t）Signal, so that the controller predicts that there is no significant lag in the control effect, thusTcuTemperature control unitThe controller is always able to generate a suitable control signal. That is to say, even if there is a significant lag, this Dynamic signalyc（t）It can also maintain the normal operation of the feedback loop, but it is averagePIDTo control processes with significant time lag, the controller output cannot be combined within the lag time The appropriate feedback signal continues to grow, leading to significant overshoot or even loss of control in the system response.

　　Three-point sampling

Through three-point sampling (material temperature point, temperature control system outlet temperature, temperature control system inlet temperature), using Guanya Refrigeration's self created model free self built algorithm and general anti lag series calculation Combining law with practice.

TcuTemperature control unitDo you all understand the principle of use?TcuThe temperature control unit is used in production equipment and placed next to the reaction kettle. You can choose according to your actual situation.
