We present a novel simplest fuzzy PID controller using a modified Takagi – Sugeno (TS) rule base. Mathematical model of the controller is derived and analyzed. The unique features of the controller are: (i) the consequent part of the rule base is closely related to the rule base of Mamdani type controller, and (ii) the proportional, integral and derivative gains vary as the output of the system...

In this paper we present a rule-based (declarative) approach for rule verification. We focus on anomalies, which may appear in rule bases, containing production rules and semantic constraints. The presented approach defines special rules, called verifier rules, which look for anomalies in business rules. The approach is flexible and easy to maintain in the sense that verifier rules can easily b...

Employing the light-cone sum rule approach in QCD, we relate the B-meson distribution amplitude to the B → π form factor at zero momentum transfer. In leading order, the sum rule is converted into a simple expression for the inverse moment λB of the distribution amplitude φ+. Using as an input the B → π form factor calculated from the light-cone sum rule in terms of pion distribution amplitudes...

The Modified Golden Rule, which relates the rate of return on capital and the growth rate of the capital stock along long-run growth paths that maximize the utility of a representative infinitely-lived consumer, is invariant to the introduction of convex capital adjustment costs. Therefore, along balanced growth paths in neoclassical optimal growth models with an exogenous long-run growth rate ...

In this study, we propose a new method to enhance the accuracy of Modified Multi-class Classification based on Association Rule (MMCAR) classifier. We introduce a Partial Rule Match Filtering (PRMF) method that allows a minimal match of the items in the rule’s body in order for the rule to be added into a classifier. Experiments on Reuters-21578 data sets are performed in order to evaluate the ...

The semantic of neural networks is not explicit and they are considered as black box systems. There are many researches investigating the area of rule extraction by neural networks. In this paper, the eclectic approach of rule extraction from a dynamic cell structure (DCS) neural network is investigated. To do this, a modified version of LERX algorithm is used for rule generation. Empirical res...

The chattering response at the MRP shadow set switching point for the controlled attitude dynamics of a rigid tumbling spacecraft using delayed state feedback control with MRPs is investigated, where the time delay is assumed to be in the measurement of the state. In addition, a strategy to reduce or completely avoid the chattering phenomena using a hysteretic boundary layer switching rule is e...
