【Abstract】 As a classical optimization,the active set method is investigated and two algorithms based on active set method are developed and implemented in aircraft control allocation,which is often transformed into constrained quadratic programming problem.Here,basic aircraft control allocation is described and formulated simply,and several methods for solving the control allocation are discussed.In addition to the two posed algorithms,several previous algorithms are also implemented for comparison.Performance and computational feasibility is evaluated using aircraft model with many more actuators,which suffering from position and rate constrains.Results by simulation show that this control allocation method is feasible,effective and successful.更多还原
