Performance Assessment of PID Controllers
Criteria based on disturbance rejection and system robustness are proposed to assess the performance of PID controllers. The robustness is measured by a two-block structured singular value, and the disturbance rejection is measured by the minimum singular value of the integral gain matrix. Examples show that the criteria can be applied to a variety of processes, whether they are stable, integra...
متن کاملPerformance Assessment and Retuning of PID Controllers for Load Disturbance Rejection
In this paper we propose an algorithm for the load disturbance rejection performance assessment of a PI(D) controller and for the retuning of the parameters in case the obtained response is not satisfactory. The technique can be applied simply by evaluating the load disturbance closed-loop response. The automatic tuning for a set-point filter is also proposed in order to address the set-point f...
متن کاملDesign of PI and PID controllers with transient performance specification
Proportional-integral-derivative (PID) controllers are widely used in industrial control systems because of the reduced number of parameters to be tuned. The most popular design technique is the Ziegler–Nichols method, which relies solely on parameters obtained from the plant step response. However, besides being suitable only for systems with monotonic step response, the compensated systems wh...
متن کاملImproving Performance of Pid Controllers Using Adaptive Control
A simple Add-On adaptive control algorithm is presented that can improve the performance of any linear timeinvariant plant controlled by PID controller. The algorithm is simple. It is proved that such algorithm always exists. The proof is constructive, that is, it is simple and straight forward to design and implement the control algorithm. The algorithm is presented as a set of equations and i...
متن کاملEasy Tuning of PID Controllers for Specified Performance
The presented method allows achieving maximum overshoot and specified settling time of the closed-loop step response. It provides a simple way to control linear stable SISO systems even if the mathematical model is unknown. Tuning rule parameters are based on one suitably chosen point of the plant frequency response obtained by sine-wave signal with specified excitation frequency, and the requi...
