Tuning of the regulator PID parameters?
Thread Content
Regarding the PID parameter tuning of DCS control systems, which we see frequently, this tuning process is mainly aimed at adjusting the parameters of the regulator. So what exactly is meant by a regulator in this context? Is there a specific physical hardware code? Such as the parameters of the control valve? What specific parameters are those of the physical devices? Are they not parameters of physical hardware, but rather parameters of mathematical relationships within software? Solve.
Asking so many questions – it seems quite professional. Why not just find a book and read it by yourself?
PID control involves adjusting the parameters of the controller: gain, integration, and differentiation
In the era before DCS systems, control system loops were built using combined gauge assemblies, and instruments called \"regulators\" were used (they were composed of electronic circuits just like other instruments, and are now referred to as \"hardware\"); this term continued to be used even after the advent of DCS systems (it actually refers to the \"PID module\" within a DCS system), although it is also called a \"controller\".
