| General note | Guided by:Dr D. M. Adhyaru With Synopsis and CD <br/>13EXTPHDE104<br/><br/>ABSTRACT:<br/>This thesis investigates the application of fractional order control methodology in the design of<br/>control systems for linear and nonlinear systems. The fractional-order control algorithm like FOPID, Adaptive Controller, Model Reference Adaptive Control (MRAC), Fractional Order MRAC(FO-MRAC), Fractional order optimal control (FOCP ), etc have been explored for the given plant. The effectiveness of soft computing technique based adaptation mechanisms for<br/>MRAC is also presented in the present work. Further, an identification technique has been proposed to find out the fractional-order transfer of the given plant. Role of the artificial<br/>intelligence-based algorithm and metaheuristic based algorithm is also explored.<br/>Since the fractional-order operator itself represents the infinite-dimensional system, it is necessary to find a suitable approximation of the fractional-order operator. A lot of research work has been carried out approximate the fractional-order operator in finite-dimensional space. Out of the many<br/>available methods and combinations available, it has been necessary to find out the appropriate approximation method for the given system. A comparative analysis based study has been carried out to select a suitable method to approximate the fractional-order operator. Using this method,<br/>all the related simulations and hardware implementation has been carried out.<br/>Most of the model-based control strategies are failed in the practical environment due to inherent nonlinearity and unknown dynamics in the system, Fractional-order modelling overcome this disadvantage. Idea is to take benefit of fractional order modelling for accurate control of the fractional-order system. A practical methodology has been suggested for the identification and<br/>control of the fractional-order control system. Results are presented, analyzed and compared for<br/>applied strategies<br/>With results, it has been observed that to fractional-order model fits better than the integer-order<br/>model. Further, it has been observed that fractional-order control algorithms outperform the integer-order control algorithms.<br/>Fractional order optimal control problem is not addressed in great depth so far. A method has been<br/>suggested to take advantage of FOCP in control of integer order dynamics and fractional-order dynamics. Results are validated on two setups. The first set up is DC motor setup and the second<br/>setup is the auto-balance robot setup. It has come out as the best of all applied strategies with improved results. The overall stability of the proposed system is proven using simple control<br/>techniques. |
