Pid Controller Tuning Thesis

An example would be a valve for cooling water, where the fail-safe mode, in the case of loss of signal, would be 100% opening of the valve; therefore 0% controller output needs to cause 100% valve opening.The overall control function can be expressed mathematically as , all non-negative, denote the coefficients for the proportional, integral, and derivative terms respectively (sometimes denoted P, I, and D).

Nevertheless, using PID for NCS has not been thoroughly investigated, especially with regard to controller tuning. Simple PID tuning rules for varying time-delay systems.

This thesis proposes several PID tuning methods, which provide robustness against the challenges of NCS, namely varying time-delays (jitter) and packet loss. In: Proceedings of the 46th IEEE Conference on Decision and Control (CDC 2007).

In practical terms it automatically applies accurate and responsive correction to a control function.

An everyday example is the cruise control on a car, where ascending a hill would lower speed if only constant engine power is applied.

The distinguishing feature of the PID controller is the ability to use the three control terms of proportional, integral and derivative influence on the controller output to apply accurate and optimal control.

The block diagram on the right shows the principles of how these terms are generated and applied.

The doctoral thesis consists of a summary and eight publications that focus on the PID controller design, tuning and experimentation in NCS.

The thesis includes a literature review of recent stability and control design results in NCS, a summary of publications and the original publications.
