چکیده
The paper presents development and tuning tehniques and solutions for PI and PID controllers, and Takagi-Sugeno fuzzy controllers with PI and PID type dynamics meant for applications which can be characterised with low order benchmark type modeles (for example electrical and hydraulic driving and positioning systems).Two type of plants and two control structures with homogenous and with non-homogenous information processing with respect to the inputs are presented, including tuning and optimization aspects. Then Takagi-Sugeno fuzzy models dedicated to a class of plants characterized by Two InputSingle Output linear time-varying systems are presented. It is offered a stability test algorithm of the fuzzy control systems involving Takagi-Sugeno fuzzy controllers, to control the accepted class of plants. The tuning methods are briefly presented in relation with a control solution for a drive system with a variable inertia strip winding system.

A New High-order Takagi-Sugeno Fuzzy Model Based on Deformed Linear Models
Amongst possible choices for identifying complicated processes for prediction, simulation, and approximation applications, high-order Takagi-Sugeno (TS) fuzzy models are fitting tools. Although they can construct models with rather high complexity, they are not as interpretable as first-order TS fuzzy models. In this paper, we first propose to use Deformed Linear Models (DLMs) in consequence pa...

The paper presents new Takagi-Sugeno fuzzy models for a class of plants characterized by Two Input-Single Output systems providing the fuzzy logic decision on the local model choice. In addition, it is provided a development method for controllers selected by Takagi-Sugeno-based decision rules to control these plants. The models and the development method are applied to speed control of electri...
متن کاملOn a Class of Control Systems with Takagi- Sugeno PI-Fuzzy Controllers
The paper proposes a new development method dedicated to a class of fuzzy control systems containing Takagi-Sugeno PI-fuzzy controllers to control SISO linear / linearized plants. The considered controllers are characterized by variable number of triangular input membership functions. The method is expressed in terms of relatively simple steps that use the prediction of the limit cycles on the ...
متن کاملAdmissibility analysis for discrete-time singular systems with time-varying delays by adopting the state-space Takagi-Sugeno fuzzy model
This paper is pertained with the problem of admissibility analysis of uncertain discrete-time nonlinear singular systems by adopting the state-space Takagi-Sugeno fuzzy model with time-delays and norm-bounded parameter uncertainties. Lyapunov Krasovskii functionals are constructed to obtain delay-dependent stability condition in terms of linear matrix inequalities, which is dependent on the low...
متن کاملIdentification of Cement Rotary Kiln in Noisy Condition using Takagi-Sugeno Neuro-fuzzy System
Cement rotary kiln is the main part of cement production process that have always attracted many researchers’ attention. But this complex nonlinear system has not been modeled efficiently which can make an appropriate performance specially in noisy condition. In this paper Takagi-Sugeno neuro-fuzzy system (TSNFS) is used for identification of cement rotary kiln, and gradient descent (GD) algori...
