Self-Tuning Fuzzy PI Controller (STFPIC)

design of an analog fuzzy logic controller chip

fuzzy logic has been developed over the past three decades into a widely applied techinque in classification and control engineering. today fuzzy logic control is one of the most important applications of fuzzy set theory and specially fuzzy logic. there are two general approachs for using of fuzzy control, software and hardware. integrated circuits as a solution for hardware realization are us...

Analytical PI Controller Tuning Using Closed-loop Setpoint Response

Recently Shamsuzzoha and Skogestad proposed a proportional-integral (PI) tuning rule for a wide range of unidentified processes. The rule relies on a closed-loop setpoint response (CSR) of a process and was developed from extensive numerical experiments. This work analytically derives a similar PI tuning rule using the CSR method. Simulations indicate that the two rules perform similarly if the...

Tuning of PI speed controller

PID controllers are very common in industrial systems applications. The tuning of these controllers is governed by system nonlinearities and continuous parameter variations. In this paper, a complete and rigorous comparison is made between two tuning algorithms. The PI controller was used in a speed control loop in a Direct Torque Control (DTC) scheme applied on an induction motor. The first me...

Self-Tuning of a Robust Fuzzy PI-PD Controller

In this paper, a simple and effective scheme for tuning of fuzzy PI-PD controller based on fuzzy logic is proposed. Here the input scaling factors are tuned online by gain updating factors where values are determined by rule base with error and change in error as inputs according to the required controlled process. The performance comparison of conventional fuzzy logic controller, auto-tuned fu...
