Adaptive Zooming Strategy in Discrete-time Implementation of Sliding-mode Control∗

The adaptive zooming strategy borrowed from the coding-decoding procedure of data transmission over the limited capacity communication channel is applied for discrete-time sliding mode control design. The proposed control strategy is numerically studied both for illustrative example and for control of 3-DOF laboratory Helicopter benchmark. The simulation results confirm low-chattering sliding mode behavior and eficiency of the proposed method.
