Takagi-Sugeno (TS) type of fuzzy models for data-driven set has attracted a great deal of attention of the fuzzy modeling community due to its satisfactory performance in various applications. In this paper, an application of TS model is described to obtain approximated input-output response of turbine-generator unit in a hydro power plant operating as an isolated system. The rule-base is generated...
In this paper, the hydro power plant dynamics is identified using fuzzy models. The plant data is generated from Pade and H-infinity approximated first, second, third and fourth-order rational transfer function models. The models are simulated as (i) gate-servo motor position and turbine speed with random load disturbance and (ii) gate position and developed turbine power. Takagi-Sugeno fuzzy model...
The state estimation of inelastic and elastic fifth-order state-space model of hydro plant is performed. The method adopted for state estimation is based on second-order polynomial approximations of a multi-dimensional interpolation formula. It is found that the state estimation of plant by this method outperforms to linear Kalman filter in terms of estimation. Then a state estimation based linear...
