Presents the application of the minimal radial basis function neural networks called minimal resource allocation neural networks (MRAN) for fault-tolerant flight controller design. Based on a study of different architectures for neural control, a simple architecture in which the MRAN controller is aiding a conventional controller is proposed. The main advantage in this scheme is that it requires no off-line training for the neural network and the scheme has good fault tolerant capabilities. The MRAN controller is illustrated for a F8 fighter aircraft longitudinal control in an autopilot mode for following velocity and pitch rate pilot commands under large parameter variations and sudden variations in actuator time constants. Results indicate that MRAN controller exhibits better performance than an earlier suggested feed forward inverse neural controller using gradient learning scheme.
