Bayesian Optimization for automatic tuning of digital multi-loop PID controllers

2015, ISA TransactionsCitation Excerpt :However, simplicity in design was the only advantage in these methods and the significant effect of interaction was still present. The independent method proposed in [16] was quite simple to apply but it had a disadvantage resulting from the negligence of how the other control loops were designed. An approach of independent design of multi-loop PI/PID was proposed in [17].
Heuristic-based multi-scale control procedure of simultaneous multi-loop PID tuning for multivariable processes
2015, Journal of Process ControlCitation Excerpt :In the independent design approach, an individual controller is designed for each loop while satisfying constraints imposed by process interactions [8]. An independent design method based on the Internal Model Control (IMC) structure was proposed by Hovd and Skogestad [9] in which, the tuning parameters are the IMC filter time constants. In this method there are n tuning parameters for a given n × n MIMO system.
Multilevel adaptive control of nonlinear interconnected systems
2015, ISA TransactionsCitation Excerpt :In this approach, the occurrence of probable failures in one part of the system will have less effect on the other parts. Some other reasons for popularity of decentralized controllers in industry are that they can be tuned separately, are easy to implement and easy for operators to understand [8,9]. Despite all the benefits of decentralized control, it has one major drawback, which is the performance deterioration [10].
