Abstract: Propulsion system overall performance seeking control (PSC) algorithm based on sequential linear programming (SLP) was studied.In SLP,a general nonlinear programming problem is solved by sequentially solving a series of linear programming problems.By continuing the linearization process,the optimum value can be found within a given tolerance.The hardware in the loop simulation is used to test the linear PSC control system real-time capability.Simulation results show that linear PSC Control System completed all operations in an airborne computer real-time and achieve substantial benefits.
