Abstract
This paper presents a design of a novel adaptive controller - online tuning modified-Grey fuzzy PID (OTMGFPID) - to deal with nonlinear systems. The OTMGFPID is a combination of a main control unit - online tuning fuzzy PID (OTFPID), and a predictor - online tuning modified-Grey predictor (OTMGP). The OTFPID controller, which is built from an adaptive proportional-integral-derivative (PID) controller based on an online tuning fuzzy-neural technique and robust checking conditions, is used to drive the system to desired targets. In addition, a smart learning mechanism (SLM) was implemented into the OTFPID in order to optimize smartly its parameters with respect to the control error minimization. The OTMGP with online tuning ability of the predictor step size based fuzzy (FPSS) is used to estimate the actual system output and to create a compensating signal corresponding to the system perturbations. The effectiveness of the proposed OTMGFPID controller has been evaluated by numerical simulations in a comparison with other typical controllers.
