| Abstract: | Based on command sensitivity,state sensitivity is defined to describe the performance of control allocation algorithm,responding to varying states within the flight envelope.The element and function of control allocation are introduced,then two classes of mixed optimization for control allocation with better real-time performance,linear programming control allocation(LPCA) and quadratic programming control allocation(QPCA),are compared with.The problem is solved by simplex algorithm and active set algorithm... |
