Incommensurate Order Fractional Optimal Control: Application to Treatment of Psychiatric Disorders

The main point of this paper is to present a time domain strategy for drug dosage to treat psychiatric disorders. A time domain model of emotion is obtainedfrom an extension of a recently developed fractional nonlinear dynamic model of happiness. First, the Fractional Optimal Control law for incommensuratemulti state systems is obtained. It will be then applied as an optimal drug administration procedure in the line of psychiatric disorders treatment. Results of this papershow that optimal control scheme is a proper approach to face the difficulties of analysis and control theincommensurate systems. It can be also clearly seen fromthe simulation results that this approach is very effective in the case that control methods are used as treatment techniques.
