Abstract :
In a stratospheric balloon experiment the orientation of the instrumentation, mainly an interferometer examining trace gases, has to be stabilized down to 140 μrad while the balloon is pitching. Due to changing process conditions an adaptive nonlinear controller for orientation stabilization is necessary. To solve the problem a new neuro-model based fuzzy controller has been developed. The neural network provides a nonlinear model of the process being controlled. The fuzzy controller is automatically generated by the neural network. A comparison of this neuro-fuzzy controller and a classical PID-controller shows the capability of the proposed approach
