“…CB consists of three elements: the first order infinite impulse response (IIR) input filter defined by one parameter (a), the PID controller in the serial form [12] defined by three parameters (q0,q1,q2) and the anti-wind-up mechanism. In such a way several CBs can constitute the whole controller or model a dynamic object [2].…”

“…Short reaction time is often a necessary condition of correctness of control system. Moreover, method proposed in this paper can be used in future not only for designing of control systems but also of hardware emulators of dynamic objects [2,[3][4][5][6][7]. Such emulators are usually used in a development process of a complex controller of a machine or an industrial process.…”

Controller design is a difficult and time consuming process. Moreover, high implementation accuracy of theoretically developed control algorithm causes high computational complexity and may result in inability of control system to work with selected time step. Short time step is often a necessary condition of correctness of control algorithm and finally of control system. These requirements may be fulfilled by use of the field programmable gate array (FPGA) as a implementation platform. However, in many cases designed controller is sensitive to inaccuracy due to limited resolution of input and output signals as well as of digital word used in implementation. All of these limitations should be taken into consideration in design stage. In this paper is proposed a method based on an evolutionary algorithm which takes into account mentioned limitations. As a result the process of controller design is performed easier and faster. Streszczenie. Projektowanie regulatora jest trudnym i czasochłonnym procesem. Ponadto implementacja opracowanego teoretycznie algorytmu sterowania niejednokrotnie skutkuje wysoką złożonością obliczeniową. Może to skutkować brakiem możliwości pracy systemu sterowania z zadanym krokiem czasowym. Oprócz wspomnianych zjawisk występują problemy związane z rozdzielczością sygnałów wejściowych i wyjściowych jak i słowa cyfrowego użytego w implementacji realizowanej w na przykład układach programowalnych FPGA. Aby powstający system działał prawidłowo wszystkie te ograniczenia powinny być uwzględnione już na etapie projektowania. W artykule przedstawiona została metoda projektowania systemu regulacji bazująca na algorytmie ewolucyjnym. Metoda ta uwzględnia wspomniane ograniczenia oraz czyni trudny i czasochłonny proces projektowania regulatora łatwiejszym i szybszym.

Abstract. Identity verification based on the dynamic signature is an important issue of biometrics. There are many effective methods to the signature verification which take into account the dynamic characteristics of the signature (e.g. velocity of the pen, the pen's pressure on the surface of the graphic tablet, etc.). Among these methods, the ones based on the so-called global features are very important. In our previous paper we have proposed new algorithm for evolutionary selection of the dynamic signature global features, which selects a subset of features individually for each user. Algorithm proposed in this paper is a faster version of the method proposed earlier. During development of the algorithm we resigned from using evolutionary selection of global features and standardized working of the classifier in the context of all users. The paper contains the simulation results for the BioSecure database of the dynamic signatures.

Abstract. In this paper a new approach for construction of neuro-fuzzy systems for nonlinear classification is introduced. In particular, we concentrate on the flexible neuro-fuzzy systems which allow us to extend notation of rules with weights of fuzzy sets. The proposed approach uses possibilities of hybrid evolutionary algorithm and interpretability criteria of expert knowledge. These criteria include not only complexity of the system, but also semantics of the rules. The approach presented in our paper was tested on typical nonlinear classification simulation problems.
