PI controller tuning for load disturbance rejection using constrained optimization

PID controller with improved load-disturbance rejection

In this paper a two-degree-of-freedom (2DOF) IMC structure is considered for integrating process with deadtime to achieve improved load-disturbance response along with the set-point response. Set-point controller is designed considering desired speed of response of the closed-loop system. The load-disturbance controller is designed through direct synthesis approach and both the controllers are ...

Robust Tuning of PID Controller With Disturbance Rejection Using Bacterial Foraging Based Optimization

In this paper, design approach of PID controller with rejection function against external disturbance in motor control system is proposed using bacterial foraging based optimal algorithm. Up to the present time, PID Controller has been used to operate for AC motor drive because of its implementational advantages in practice and simple structure. However, it is not easy to achieve an optimal PID...

Reliability based multiobjective optimization design procedure for PI controller tuning . ?

In this work, we propose an hybrid multi-objective optimization design procedure for PI controller tuning. This procedure focuses on reliability-based optimization instances, where Montecarlo methods are used to evaluate quantitatively the performance degradation of a controller, due to unexpected or unmodeled dynamics. The procedure is evaluated on a non-linear Peltier process. The presented r...

Tuning of PI speed controller

PID controllers are very common in industrial systems applications. The tuning of these controllers is governed by system nonlinearities and continuous parameter variations. In this paper, a complete and rigorous comparison is made between two tuning algorithms. The PI controller was used in a speed control loop in a Direct Torque Control (DTC) scheme applied on an induction motor. The first me...
