Design of disturbance-rejection controllers for linear multivariable discrete-time systems using entire eigenstructure assignment

The method of entire eigenstructure assignment constitutes a powerful new method for the design of on-board digital flight controllers. This fact is demonstrated by the presentation of a technique for the design of finite settling time disturbance-rejection controllers for linear multivariable discrete-time systems incorporating digital integrators. The computational attractiveness of the method of entire eigenstructure assignment is illustrated by designing a time-optimal disturbance-rejection controller for the lateral dynamics of the F-4 aircraft. The transient-response characteristics of the controlled aircraft are illustrated by the presentation of the results of simulation studies for a number of sampling periods when the aircraft is subjected to a very severe yawtorque disturbance.
