A fuzzy sliding-mode control with rule adaptation design approach with decoupling method is proposed. It provides a simple way to achieve asymptotic stability by a decoupling method for a class of uncertain nonlinear systems. The adaptive fuzzy sliding-mode control system is composed of a fuzzy controller and a compensation controller. The fuzzy controller is the main rule regulation controller...

The real time computer for controlling and regulating the FNAL Main Ring power supplies has been upgraded with a new learning control system. The learning time of the system has been reduced by an order of magnitude, mostly through the implementation of a 95 tap FIR filter in the learning algorithm. The magnet system consists of three buses, which must track each other during a ramp from 100 to...

This paper presents a novel power supply system based on the use of fuzzy inference logic to improve control renewable energy sources. The comprises solar and wind sources, an accumulator battery is used as additional source. procedure for parallel connection multiple sources provides stable optimal charging accumulative element. Renewable are connected in using two serial converters controlled...

one of the main problems in wind energy conversion system (wecs) is how to achieve maxim­u­m output power in different wind speeds. maximum methods for maximum power point tracking in wind energy conversion syst­e­ms require the knowledge of system characteristics and mechanic sensors. so, using these methods practically will follow with high price and an abundant difficulties. in this paper, n...

Since the performance of the teleoperation systems can be considerably degraded by time-delay of communication channels and uncertainty in various parts of such systems, the main objectives of the controller design in loads of different structures of the bilateral teleoperation system are to preserve stability and tracking performance of these systems in spite of aforementioned sources of uncer...

In many industrial fermentation processes oxygen availability is the main limiting factor for product production. Typically the dissolved oxygen (DO) concentration decreases continuously at the beginning of the batch until it reaches a critical level where the oxygen transfer rate is very close to the vessel’s maximum transfer capacity. The process may be further driven close to this sensitive ...

This paper discusses some of the issues related to board level testing. The main interest is focused on the boundary scan technique combined with an on board test controller, and the problems of how complete systems with several boards should be tested in a hierarchial test environment. Test controller design issues are discussed, together with a description of which functionality a test contro...

The swing-up control of a triple pendulum on a cart is presented, where the controller is based on a two-degrees-of-freedom scheme consisting of a nonlinear feedforward controller and an optimal feedback controller. The point-to-point transition task is treated as a nonlinear two-point boundary value problem with free parameters resulting from the suitably projected inputoutput dynamics. The ma...
