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.
