A Hybrid of Fuzzy and Proportional-Integral-Derivative Controller for Electro-Hydraulic Position Servo System
Problem statement: While classical PID controllers are sensitive to variations in the system parameters, Fuzzy controllers do not need precise information about the system variables in order to be effective. However, PID controllers are better able to control and minimize the steady state error of the system. To enhance the controller performance, hybridization of these two controller structure...
متن کاملA Hybrid of Fuzzy and PID Controller for Servo Electro-Hydraulic System
In industrial applications, the dynamic characteristics of the servo-hydraulic system are always complex and highly nonlinear. Moreover, there are too many uncertainties in it; for example, the viscosity of oil, the bulk modulus, the oil volume, the system pressure, the wear and the cavitations. The loading conditions are usually rather unsteady, and the loading forces change in a wide range du...
متن کاملResearch of the Electro-hydraulic Servo System Based on RBF Fuzzy Neural Network Controller
This article describes the composition and working principle of electro-hydraulic position servo control system, and establishes a systematic mathematical model. This article presents a controller which is based on Fuzzy neural networks for an electro-hydraulic speed governor. The design process of the RBF Fuzzy neural network control is introduced in detail. This controller which combines the ...
متن کاملDesign of a hybrid fuzzy logic proportional plus conventional integral-derivative controller
This paper presents approaches to the design of a hybrid fuzzy logic proportional plus conventional integralderivative (fuzzy P+ID) controller in an incremental form. This controller is constructed by using an incremental fuzzy logic controller in place of the proportional term in a conventional PID controller. By using the bounded-input/bounded-output “small gain theorem,” the sufficient condi...
متن کاملHybrid Fuzzy Logic Proportional Plus Conventional Integral-Derivative Controller for Permanent Magnet Brushless DC Motor
This paper presents a hybrid fuzzy logic proportional plus conventional integral-derivative controller (FP+ID) for the speed control of permanent magnet brushless dc (PMBLDC) motor. Though, PID controllers are commonly used in practice, they have failed to perform satisfactory under nonlinearity, load disturbances, parameter variation etc. In this paper, the performance of the permanent magnet ...
