  • In the seeking control of multivariable aero-engine,general optimization algorithm may find the locally optimal solution.An improved algorithm based on particle swarm optimization (PSO) and support vector regression (SVR) was applied to aero-engine stability seeking control,setting the lower limits for surge margin to keep aero-engine working stably.The working point with minimum surge margin was searched globally.The simulation results show that the designed stability control algorithm could reduce the surge margin while keeping the thrust constant and reduce the turbine inlet temperature and specific fuel consumption effectively.
