Valves can be electronically actuated and can control hydraulic power quickly and accurately. There are sensors capable of transforming fluid power and mechanical variables into electronic signals. Appropriate control strategies and sophisticated control algorithms are required to overcome the disadvantages and nonlinear dynamic behavior of hydraulic drives. This is successfully obtainable only by implementation of digital control systems designed on the basis of modern control theory. Several types of conventional PID-controllers, adaptive controllers and fuzzy logic controllers have been developed. The purpose of the research work described in this paper was to explore the possibilities of inserting self-learning and self-organising characteristics into control algorithms for control of electrohydraulic drives. The proposed reinforcement learning method enables a faster adaption on parameter changes than some traditional learning methods. The results of experimental investigations are also shown.","PeriodicalId":227402,"journal":{"name":"ISIE '99. Proceedings of the IEEE International Symposium on Industrial Electronics (Cat.

The control law is derived by means of a circuit-oriented procedure. After establishing a large-signal circuit model for the boost regulator including state-feedback, conditions for passivity in the resulting two-port are studied. As a consequence, a control law is directly derived from two-port passivity conditions, this ensuring regulator global stability even if the control saturation is taken into account. Subsequently, a linear analysis is performed in order to design the desired dynamics and robust behavior of the switching regulator. The linear analysis shows that only one feedback gain is necessary, provided that the coordinates of the equilibrium point are known. The use of regulator root locus, gain margin and phase margin diagrams as a function of the feedback gain allows to choose the proper value of this gain solving a certain trade-off for good dynamic response and robust behavior. ACSL simulations verify the analytical predictions.","PeriodicalId":227402,"journal":{"name":"ISIE '99. Proceedings of the IEEE International Symposium on Industrial Electronics (Cat.

For proper operation of the motor drive system certain parameters have to be set-up. Usually interaction between the human and motor drive controller is accomplished using an embedded keyboard and display. Usually there are several menus and every parameter is accessible with a corresponding code. Because PCs are available everywhere, the authors decided to implement the user interface on a PC running under the MS Windows operating system. The main benefit of such an interface is a simplified parameter setup. The PC and controller are connected with an RS232 cable. Parameter set-up can be downloaded to the controller, uploaded from the controller, saved into file and loaded from it. Besides parameter management, the user interface makes it possible to display selected variables and plot online time responses. There are also functions for parameter identification of the machine. Because the program in a motor drive controller is stored in the FLASH memory and hardware supports in-circuit programming, another function that supports firmware update was added. This way the software update is very simple and program customizing for specific requirements can be done easily.","PeriodicalId":227402,"journal":{"name":"ISIE '99.

The motivation behind the use of neuro-fuzzy approaches is based on the complexity of real life systems, ambiguities on sensory information or time varying nature of the system under investigation. In this respect, neuro-fuzzy design approaches combine architectural (by neural networks) and philosophical (by fuzzy systems) aspects of an expert resulting in an artificial brain, which can be used as an identifier or a controller. It is known that the fuzzy inference systems and neural networks are universal approximators. An architecture with an appropriate learning strategy can teach any mapping to such a system with a predefined realization error bound. The most questionable quality in the use of neuro-fuzzy architectures is the stable training. This tutorial considers various neuro-fuzzy structures and gradient based training procedures. Consideration is given to stabilization of training dynamics.","PeriodicalId":227402,"journal":{"name":"ISIE '99. Proceedings of the IEEE International Symposium on Industrial Electronics (Cat.

The circuit parameters of the electronic ballast to be determined are assigned as the control variables in the orthogonal arrays, and the average effects corresponding to each control variable are calculated from the circuit performances which are obtained from experimental tests. In accordance with the inferential rules, the average effects are used as the observational indexes to adjust the levels of the control variables for the subsequent orthogonal array. Through manipulating consecutive orthogonal arrays step by step, the applicable ranges of circuit parameters are shrunk, and then the region with desired output performances can be approached. The design procedure and the inferential rules are illustrated by an example of the electronic ballast with the self-excited series resonant inverter. In the design example, one can find 8 combinations of circuit parameters with the desired output performances from 5 steps of orthogonal array manipulation.","PeriodicalId":227402,"journal":{"name":"ISIE '99.
