The concept comes from interpolation forms of fuzzy control introduced in Chapter 8. First, we define monotonicity of control rules, and we prove that the monotonicity of interpolation functions of fuzzy control is equivalent to the monotonicity of control rules. This means that there is no contradiction among the control rules under the condition for the control rules being monotonic. Then the structure of the contraction-expansion factor is discussed. At last, based on variable universes, we present three models of adaptive fuzzy control, namely, an adaptive fuzzy control model with potential heredity, adaptive fuzzy control model with obvious heredity and adaptive fuzzy control model with successively obvious heredity.","PeriodicalId":239984,"journal":{"name":"Fuzzy Neural Intelligent Systems","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116814066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Beginning with the XOR problem, we discuss the mathematical essence and the structures of functional-link neural networks. Extending this idea, we give the visualization means of mathematical methods. We also give neural network representations of linear programming and fuzzy linear programming. A single-layer neural network, first studied by Minsky and Papert, was named perceptron in 1969 [l]. It is well known that a single-layer perceptron network cannot solve a nonlinear problem. A typical problem is the Exclusive-OR (XOR) problem. Generally, there are two approaches to solve this nonlinear problem by modifying the architecture of this single-layer perceptron. The first one is to increase number of the hidden layers, and the second one is to add higher order input terms. There are numerous applications using either of these approaches [2-41. Here we will illustrate that these two approaches, in fact, are essentially mathematical equivalence. is the same neuron with a higher order term, 2 1 .x2 shows a simple neuron with two inputs.","PeriodicalId":239984,"journal":{"name":"Fuzzy Neural Intelligent Systems","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124729285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The class of uncertain phenomena can further be subdivided into random (stochastic) phenomena and fuzzy phenomena. Therefore, we have three categories of phenomena and their associated mathematical models: 1. Deterministic mathematical models-This is a class of models where the relationships between objects are fixed or known with certainty. 2. Random (stochastic) mathematical models-This is a class of models where the relationships between objects are uncertain or random in nature. 3. Fuzzy mathematical models-This is a class of models where objects and relationships between objects are fuzzy. The main distinction between random phenomena and fuzzy phenomena is that random events themselves have clear and well-defined meaning, whereas a fuzzy concept does not have a precise extension because it is hard to judge if an object belongs to the concept. We may say that randomness is a deficiency of the law of causality and that fuzziness is a deficiency of the law of the excluded middlc. Probability theory applies the random concept to generalized laws of causality-laws of probability. Fuzzy set theory applies the fuzzy property to the generalized law of the excluded middle-the law of membership from fuzziness. Probability reflects the internal relations and interactions of events under certain conditions. It could be very objective if a stable frequency is available from re-","PeriodicalId":239984,"journal":{"name":"Fuzzy Neural Intelligent Systems","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127980699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its dynamics are very complicated and coupled with the non-minimum phase nature due to the non-collocated construction of the sensor and actuator. This gives rise to difficulty in the control of a flexible arm. In particular, the control of a flexible arm usually suffers from control spillover and observation spillover due to the use of a linear and approximate model. The robustness and reliability of the fuzzy control have been demonstrated in many applications, particularly, it is perfect for a nonlinear system without knowing the exact system model. However, a fuzzy control usually needs a lot of computation time. In order to alleviate this restraint, a simplified fuzzy controller is developed for real-time control of a flexible robot arm. Furthermore, the self-organizing control based on the simplified fuzzy controller is also developed. The simulation results show that the simplified fuzzy control can achieve the desired performance and the computation time is less than 10 m s so that the real-time control is possible.","PeriodicalId":239984,"journal":{"name":"Fuzzy Neural Intelligent Systems","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121865714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
