  • Page 87: Control Basics

    6.8.1 Control basics Definition A brief explanation of terms Actuating - Initial value of the controller to compensate for the differ- signal ence between the actual value and target value (control deviation). PID con- - The PID controller operates with extreme speed and preci- troller sion and consists of a P, I and D-component.
  • Page 88 The viscosity of the heat transfer liquid changes drastically with the tem- perature. At low temperatures, liquids are more viscous. The control quality is therefore generally poorer at low temperatures. For this reason, the control setting should be towards the lower end of the temperature range. If the temperature range of an application is -20 to 80 °C, for example, a control setting of -10 to 20 °C is most suitable.

  • Page 89: Overview Of Internal Control Parameters

    In the case shown here, the preset I-component is too large (parameter Tn too small, Tn must be increased). The I-component integrates the control deviation until it becomes 0. If integration proceeds too rapidly, the actuating signal, i.e. the output signal of the controller, is too large. As a result, the actual value fluctuates (fading) around the target value.

  • Page 90: Overview Of External Control Parameters

    6.8.3 Overview of external control parameters The control system for the external actual value is designed as a 2-stage cas- cade controller to improve guidance behavior and consists of a guide con- troller (external controller) and a slave controller (internal controller). The temperature of the relevant consuming unit T is also required.
