查询词典 generating function

In order to solve this problem, a control strategy is developed. A control algorithm to suppress negative sequence current through ASVG caused by slight asymmetry of system is also developed based on the modeling method in function of switchings and the definition of instantaneous negative sequence voltage. The ASVG can generate a negative sequence voltage component against that in the system while it generating positive sequence voltage with this algorithm.

The Frechet derivative of the cost function is determined via the solution of an adjoint partial differential equation, and the boundary shape is then modified in a direction of descent. This process is repeated until an optimum solution is approached. The advantage is that the cost function variation is independent of the flow field variation, with the result that the gradient of cost function with respect to arbitrary number of design variables can be determined without the need for additional flow-field evaluations. So each design cycle requires the numerical solution of both the flow and the adjoint equations leading to a computational cost roughly equal to the cost of two flow solutions.
