| Popis: | A chattering free adaptive integral sliding mode control (AISMC) for a nuclear research reactor system in the presence of system uncertainties and input perturbation is presented. The proposed control method ensures finite time stability and also eliminates the chattering phenomenon. Also, using a deadzone technique, the upper bound of unknown system uncertainty can be estimated. The proposed AISMC can compensate for a reactivity feedback term significantly affecting the reactor system in the form of input perturbation, which is not possible in the case of integral sliding mode control (ISMC). Through simulation results, the effectiveness of the proposed controller is compared with the ISMC method for a nuclear research reactor system, and the effectiveness of the proposed control method is confirmed. |
