| dc.description.abstract | In general, the problem posed by Optimal Control Theory is to provide a given system, Z, with an appropriate input, so that the system achieves a performance which exhibits certain desired characteristics. For relatively few requirements, closed form mathematical solutions may often be possible. If however, the solution is not feasible, a suboptimal scheme must be used. In fact, such a scheme may be preferable simply because it may be easier to implement. For example, a two-step procedure was proposed in [1], where a feedback matrix is used to transfer the system from some initial state to the vicinity of the desired state in minimum time. Then a second matrix is switched on to guarantee maximum stability. In [2] a closed loop, approximately time-optimal strategy was developed for a class of linear systems with a total effort constraint. | |
