Fuzzy gain scheduling of PID controller for stiction compensation in pneumatic control valve
Inherent nonlinearities like, deadband, stiction and hysteresis in control valves degenerate plant performance. Valve stiction standouts as a more widely recognized reason for poor execution in control loops. Measurement of valve stiction is essential to maintain scheduling. For industrial scenarios, loss of execution due to nonlinearity in control valves is an imperative issue that should be t...
متن کاملImproving the pneumatic control valve performance using a PID controller
Pneumatic control valves are still the most used in process industries due to their low cost and simplicity. This paper presents a design procedure of a PID controller for a pneumatic control valve. For comparison, P and PI controllers are also utilized for the control valve. The bond graph method is used to model the control valve, in order to compare the response characteristics of the valve....
متن کاملIMC based tuning method of PID controller for DC motor speed control
For improvement of transient response of the error signal all the closed loop control system requires the controller. The simplicity, robustness and ease of implementation has attracted the use of Proportional, Integral and Derivative (PID) controllers. Though the tuning of PID controllers in real time is quite difficult and moreover it lacks the disturbance rejection capability. Internal model...
متن کاملA Unified IMC based PI/PID Controller Tuning Approach for Time Delay Processes
This paper proposes a new PI/PID controller tuning method within filtered Smith predictor (FSP) configuration in order to deal with various types of time delay processes including stable, unstable and integrating delay dominant and slow dynamic processes. The proposed PI/PID controller is designed based on the IMC principle and is tuned using a new constraint and without requiring any approxima...
متن کاملA New Tuning Method for PID Controller
The paper presents development of a new tuning method for fractional order PID controller for the systems which have integer order transfer functions. All the parameters of the controller, namely proportional gain kp, integral gain ki, derivative gain kd, fractional order of integrator λ and fractional order of differentiator μ can be obtained by using this method. It is clearly shown that the ...
