this paper presents a gain scheduled autopilot for pitch channel of a flying vehicle. the selected method is based on polynomial fuzzy systems. the method does not involve linearization about operating point. first the polynomial fuzzy model of pitch channel of the flight body is derived. next, using polynomial fuzzy system methodology the controller is design such that the outputs of the nonli...

In this paper, a new type of multi-variable compensation control method for the wind energy conversion systems (WECS) is presented. Based on wind energy conversion systems, combining artificial neural network (ANN) control and PID, a new type of PID NN intelligent controller for steady state torque of the wind generator is designed, by which the steady state torque output is regulated to track ...

Bolinger, Ohala, Morton and others have established that vocal pitch height is perceived to be associated with social signals of dominance and submissiveness: higher vocal pitch is associated with submissiveness, whereas lower vocal pitch is associated with social dominance. An experiment was carried out to test this relationship in the perception of non-vocal melodies. Results show a parallel ...

Pitch is a perceptual correlate of periodicity. Sounds with distinct spectra can elicit the same pitch. Despite the importance of pitch perception, understanding the cellular mechanism of pitch perception is still a major challenge and a mechanistic model of pitch is lacking. A multi-stage neuronal network model is developed for pitch frequency estimation using biophysically-based, high-resolut...

The response control of a very large floating structure (VLFS) is crucial issue that affects the stability and safety structure. This paper presents vibration method for stabilizing motion multi-modular VLFS by using set stiffness-adjustable connectors. proposed connector consists cylindrical spring with an embedded actuator, making its stiffness adjustable. In case study, layout such connector...

The reconstructed speech quality in a low bit-rate CELP coder is very dependent on the performance of the pitch filter. In this paper, we present an improved pitch filter, a fractional pseudethree-tap pitch synthesis filter, which performs better than a conventional one-tap pitch filter. We discuss the frequency response of the improved pitch filter. We explore stability issues for three-tap pi...

This study investigated the relationship between the production of Japanese stops by Korean speakers and word pitch pattern. Both Korean and Japanese languages have stops, but they have different phonetic characteristics: Japanese has voiced and voiceless stops whereas Korean has three stops (aspirated, tense and lax), but no contrast in voicing. Korean stops are also associated with the pitch ...

In this paper, a new modified average magnitude difference function (MAMDF) is proposed which is robust for noise-corrupt speech pitch estimation. The traditional technology in pitch estimation can easily give rise to the problem of detecting error pitch period. And their estimation performance behaves badly with the occurrence of background noise. In the process of calculation on speech sample...

This paper presents a novel system for multi-pitch tracking, i.e. estimate the pitch trajectory of each monophonic source in a mixture of harmonic sounds. The system consists of two stages: multi-pitch estimation and pitch trajectory formation. In the first stage, we propose a new approach based on modeling spectral peaks and non-peak regions to estimate pitches and polyphony in each single fra...
