A novel and more robust controller is proposed, viz a numerical-based fuzzy PID controller or extremities PID controller, which combines classical PID concepts with fuzzy arithmetics.Abstract:
The employment of PID controllers for automated processes has been widely accepted in industry. The main problems associated with classical PID controllers are tuning and robustness in case of changes in system conditions. In this paper, a novel and more robust controller is proposed, viz a numerical-based fuzzy PID controller or extremities PID controller, which combines classical PID concepts with fuzzy arithmetics. For the purpose of investigating the basic performance of the newly developed controller, two laboratory-scale plants are used, viz a simple series RLC network and a microcomputer-based dual-converter DC drive. Experimental results, including comparisons with a classical PID controller, are also presented. >read more

An Experiment in Linguistic Synthesis with a Fuzzy Logic Controller
E.H. Mamdani,S. Assilian +1 more
TL;DR: Fuzzy logic is used to convert heuristic control rules stated by a human operator into an automatic control strategy, and the control strategy set up linguistically proved to be far better than expected in its own right.
