Control Surfaces

Control laws have been designed for a high performance fighter aircraft using robust inverse dynamics estimation (RIDE) with the aim of providing good control at high angles of attack. This necessitates the use of thrust vectoring in flight conditions where aerodynamic control surfaces become ineffective. It is shown that the RIDE controller is able to transfer smoothly from using the aerodynamic surfaces to thrust vectoring during post-stall manoeuvring. The RIDE controller is structured so as to estimate the inverse dynamics of the aircraft and gives the designer freedom to assign the dynamics of the controlled states. Simulation results demonstrate that RIDE provides a simple method for the design of control laws which give specified response characteristics across the flight envelope and are robust to plant variations.

Safe Control

A novel control algorithm involving a robust inverse dynamics estimation (RIDE) is presented. It is shown how the control algorithm can be used in conjunction with a new safe criterion to result in the optimal and safe control algorithm (OSCA). The OSCA control algorithm is applied to the control of a high performance missile, where it is shown to provide excellent performance in terms of tight non-interacting and safe control in the presence of actuator saturation.
