The article analyses a auto-tuning method for a fuzzy PID controller based on the relay experiment. The algorithm was implemented and tested on a real plant for redox agent stabilisation in a paper mill. Experiments have discovered some unsolved, practical problems which were discussed in the paper i.e. determination of the ON-OFF parameters, the non-shocked switching from the ON-OFF tuning alg...

This paper demonstrates the feasibility of constructing fault-containing, self-stabilizing protocols that allow the user to ne-tune the performance of the protocols, via the choice of values for certain program parameters. Based on the fault-history of the protocol, the user can choose appropriate values for program parameters and select desirable performance guarantees from various classes of ...

The PID trajectory tracking controller for Lagrangian systems shows performance limitation imposed by inverse dynamics according to desired trajectory. Since the equilibrium point cannot be defined for the control system involving performance limitation, we define newly the quasiequilibrium region as an alternative for equilibrium point. This analysis result of performance limitation can guide ...

In this paper method of design of self-tuning fuzzy PID controller is addressed, proposed and tested. Fuzzy logic is used to tune each parameter of PID controller. The proposed controller is tested in control of the thermo-optical plant. This paper deals with theoretical and practical methodology, offering approaches for control design and its successful application.

Control of the interacting multivariable systems can be in the simplest way realized by single input single output PID/PI controllers (so called decentralized control). When model of the process is not a priori known, basic information about system can be obtained by relay autotuner. Controllers tuning is then realized in a few iterations, e.g. by sequential method. This approach may be improve...

We are using bandit-based adaptive operator selection while autotuning parallel computer programs. The autotuning, which uses evolutionary algorithm-based stochastic sampling, takes place over an extended duration and occurs in situ as programs execute. The environment or context during tuning is either largely static in one scenario or dynamic in another. We rely upon adaptive operator selecti...

. A set of different versions of the Swedish folk-tune "Fiskeskarsvisan" collected by Moberg i s studied a s regards the question why they a r e felt to be melodically similar. The observations of common elements made in an analysis of the melodies a r e integrated into a rule system by means of which new versions of the folk-tune can be generated. The rule system shows that signaling the const...

the purpose of the present study is to examine the effects of ego depletion on arousal of elite iranian swimmers. the sample comprised elite swimmers invited to the national swimming team as focused and semi focused (36 subjects). the research design was as pre- and post-test—in two phases of ego depletion conditions and the lack of ego depletion conditions in two experimental and control group...
