Passive Torque Simulator (PTS) is an important ground based hardware tester simulator used for qualification of flight actuation system under aerodynamics torque loading .In this work extra torque disturbance due to actuator motion under test is analyzed and fuzzy Backstepping control with online parameters tuning scheme is proposed. Since extra torque affects both transient and steady state pe...

To plan a water resources system, fuzzy theory is introduced to handle uncertain future information. Representing runoff hydrograph and future water demand with fuzzy membership functions, the optimal site and scale of the system are decided through fuzzy linear programming. Then the construction schedule is calculated through fuzzy dynamic programming, under the conditions of limited finance a...

Statistical language model is very important to speech recognition. To a system of special topic, domain dependent language model is much better than general model. There are two problems in traditional method to train topic dependent model: 1. The corpus of special topic is not as enough as general corpus. 2. An individual article always relates to more than one topics, traditional method has ...

the oxidative coupling of methane (ocm) performance over na-w-mn/sio2 at elevated pressures has been simulated by adaptive neuro fuzzy inference system (anfis) using reaction data gathered in an isothermal fixed bed microreactor. in the designed neuro fuzzy models, three important parameters such as methane to oxygen ratio, gas hourly space velocity (ghsv), and reaction temperature were conside...

Fuzzy sets are naturally ordered by the subsethood relation A ⊆ B. If we only know which set which fuzzy set is a subset of which – and have no access to the actual values of the corresponding membership functions – can we detect which fuzzy sets are crisp? In this paper, we show that this is indeed possible. We also show that if we start with interval-valued fuzzy sets, then we can similarly d...

A b s t r a c t Adaptive behavioral capabilities are necessary for robust rover navigation in unstructured and partiallymapped environments. A control approach is described which exploits the approximate reasoning capability of fuzzy logic to produce adaptive motion behavior. In particular, a behavior-baaed architecture for hierarchical fuzzy control of microrovers is presented. Its structure i...
