Mixed-signal Vlsi Design of Adaptive Fuzzy Systems
نویسندگان
چکیده
Hardware realization of adaptive fuzzy systems is discussed in this paper. A highly-parallel architecture based on an active-rule driven scheme is considered so that only the parameters associated with the active rules take part in the inference and learning phases. Mixed-signal circuits are used to implement a gradient-descent algorithm for tuning consequents’ values and a weight perturbation method to adjust suitably chosen antecedents’ parameters. Several applications of adaptive fuzzy chips are discussed showing that low-cost realizations are feasible.

Design Space Tradeoff in VLSI Implementations of Mixed-Signal Neuro-Fuzzy Processors
Mixed-signal VLSI design provides a tradeoff between the fast and compact but fixed analog implementations of neuro/fuzzy feedforward algorithms and the programmable but area and power consuming digital counterparts. In this paper, a sequentiality study of such systems is performed. Basic blocks for sequential mixed-signal neural and fuzzy computing are proposed, and two sequential example proc...

AbstructWe present an asynchronous mixed analog-digital VLSI architecture which implements the Fuzzy Adaptive Resonance Theory (Fuzzy ART) algorithm. Both classification and learning are performed on-chip in real-time. Unique features of our implementation include: an embedded refresh mechanism to overcome memory drift due to charge leakage from volatile capacitive storage; and a recoding mecha...

In this paper, an adaptive fuzzy control scheme is proposed for a class of perturbed strict-feedback nonlinear systems with unknown discrete and distributed time-varying delays, and the proposed design method does not require a priori knowledge of the signs of the control gains.Based on the backstepping technique, the adaptive fuzzy controller is constructed. The main contributions of the paper...
متن کاملDesign of robust carrier tracking systems in high dynamic and high noise conditions, with emphasis on neuro-fuzzy controller
The robust carrier tracking is defined as the ability of a receiver to determine the phase and frequency of the input carrier signal in unusual conditions such as signal loss, input signal fading, high receiver dynamic, or other destructive effects of propagation. An implementation of tight tracking can be understood in terms of adopting a very narrow loop bandwidth that contradict with the req...
متن کاملAdaptive Fuzzy Dynamic Sliding Mode Control of Nonlinear Systems
Two phenomena can produce chattering: switching of input control signal and the large amplitude of this switching (switching gain). To remove the switching of input control signal, dynamic sliding mode control (DSMC) is used. In DSMC switching is removed due to the integrator which is placed before the plant. However, in DSMC the augmented system (system plus the integrator) is one dimension bi...
