Numerical Analyses and a Nonlinear Composite Controller for a Real-Time Ground Aerodynamic Heating Simulation of a Hypersonic Flying Object

This paper contains two parts: numerical analyses and a control method. The of hypersonic flying object’s aerodynamic heating environment are based on three different two-dimensional outflow fields via finite element calculations. Then, the reference temperature trajectories object obtained. other one is an intelligent proportional-derivative (IPD) with nonlinear global sliding mode (NGSMC) extended state observer (NESO) for real-time ground simulation object, named thermal-structural test quartz lamp heaters. composite controller made sub-components: model free frame that independent system dynamic along ultra-local model; NESO lumped disturbances observation; integral function observation errors compensation. flight from Mach number 0.6 to 5.0, between altitude 31,272 m 13,577 m. comparative results demonstrate some superiorities proposed in terms tracking robustness.
