Abstract.
A new control method is presented in this paper. The control employs a variant of fuzzy sliding mode, optimized by a genetic algorithm. Proposed controller has many advantages, such as satisfactory control performance under a wide range of operating conditions and parameter variations, a faster response than conventional controllers, suppressed chattering phenomenon and satisfactory control for nonlinear systems. The experimental results verify the efficiency, excellent performance, and robustness of such a control in the case of the experimental servo system.
Key Words:
sliding mode control, fuzzy control, genetic algorithm, DC servo motor.
UPRAVLJANJE U FAZI KLIZNOM REŽIMU SA DODATNOM FAZI UPRAVLJAČKOM KOMPONENTOM
U ovom radu je predstavljen novi metod upravljanja. Upravljanje predstavlja varijantu fazi kliznog režima, optimizovanu genetičkim algoritmom. Predloženi regulator ima mnoge prednosti, kao što su zadovoljavajuće performanse u širokom opsegu uslova rada i varijacije parametara, brži odziv nego kod konvencionalnih regulatora, potisnuti problem četeringa i zadovoljavajuće upravljanje nelinearnim sistemima. Eksperimentalni rezultati potvrđuju efikasnost, dobre performanse i robusnost ove metode upravljanja u slučaju eksperimentalnog servo sistema.
Ključne reči:
