Performance Comparison of H-infinity and LQR Controllersfor the Pressure Regulation of a Hypersonic Wind Tunnel
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 3
Abstract
Hypersonic wind tunnels are used to study the effect of air moving past the fighter planes, space vehicles and similar specimens under test. This paper aims to compare the performance of a h-infinity controller with that of a linear quadratic regulator (LQR) controller for regulating the pressure inside the settling chamber of a hypersonic wind tunnel. The linear model for both the controllers is one and the same and it is state controllable and observable. The h-infinitycontroller design is based on the selection of weighing function whereas the design of the LQR controller depends on theselection of optimal state feedback controller gain matrix. Performance comparison of both the controllers is carried out based on the settling time, peak overshoot and rise time. Simulation results show that h-infinity controller has bettersettling time compared to LQR controller.
