Global sampled-data stabilization for a class of nonlinear systems with arbitrarily long input delays via a multi-rate control algorithm

作者:

Highlights:

• Controller design is based on sampled-data equivalent models.

• Larger sampling periods can be allowed in the stable operation of closed-loop system.

• A discrete-time predictor is constructed to compensate input delays of arbitrary length.

• Approximate controllers provide better control performance than emulation control schemes.

• Lower order approximate predicted states need only to be computed.
