In applied mathematics , the pseudospectral knotting method is a generalization and enhancement of a standard pseudospectral optimal control pseudospectral method for optimal control . The concept was introduced by Ross and Fahroo ref name RF1 Ross, I. M. and Fahroo, F., Pseudospectral Knotting Methods for Solving Optimal Control Problems, Journal of Guidance, Control and Dynamics, Vol. 27, No. 3, pp. 397 405, 2004. ref in 2004, and forms part of the collection of the Ross Fahroo pseudospectral method s. Definition According to Ross and Fahroo a pseudospectral PS knot is a double Lobatto point i.e. two boundary points on top of one another. At this point, information such as discontinuities, jumps, dimension changes etc. is exchanged between two standard PS methods. This information exchange is used to solve some of the most difficult problems in optimal control known as hybrid optimal control problems. ref name RD1 Ross, I. M. and D Souza, C. N., A Hybrid Optimal Control Framework for Mission Planning, Journal of Guidance, Control and Dynamics, Vol. 28, No. 4, July August 2005, pp. 686 697. ref In a hybrid optimal control problem, an optimal control problem is intertwined with a graph theory graph problem . A standard pseudospectral optimal control method is incapable of solving such problems however, through the use of pseudospectral knots, the information of the graph can be encoded at the double Lobatto points thereby allowing a hybrid optimal control problem to be discretized and solved using powerful software such as DIDO optimal control DIDO .
