“…This limits the use of the methods and performance of this method in complex industrial systems is therefore unknown. Similarly, Nudelman and Kulesky in [7] have shown another PID tuning scheme for the specific purpose of controlling power-station loops. Kristiansson et al [8] have shown methods for optimal PI and PID parameter tuning by utilizing the fact that during optimization, to find the parameters, the high frequency pole must be incorporated for the tuned PI(D) to be robust.…”

i ABSTRACT Proportional-Integral-Derivative (PID) controllers are a versatile category of controllers that are commonly used in the industry as control systems due to the ease of their implementation and low cost. One problem that continues to intrigue control designers is the matter of finding a good combination of the three parameters -P, I and D of these controllers so that system stability and optimum performance is achieved. Also, a certain amount of robustness to the process is expected from the PID controllers. In the past, many different methods for tuning PID parameters have been developed. Some notable techniques are the ZieglerNichols, Cohen-Coon, Astrom methods etc. For all these techniques, a simple limitation remained with the fact that for a particular system, there can be only one set of tuned parameters; i.e. there are no degrees of freedom involved to readjust the parameters for a given system to achieve, for instance, higher bandwidth. Another limitation in most cases is where a controller is designed in continuous time then converted into discrete-time for computer implementation. The drawback of this method is that some robustness due to phase and gain margin is lost in the process.In this work a method of tuning PID controllers using a loop-shaping approach has been developed where the bandwidth of the system can be chosen within an
