Question

Advantages and disadvantages of sliding mode control

Answer 1

The sliding mode control approach is assumed to be one of the efficient tools to design robust controllers for complex high order non linear dynamic plant operating under uncertain conditions.

Advantages:

# Controller design provides a systematic approach to the problem of maintaining stability & consistent performance in the face of modeling imprecision.

# Possibility of stabilizing some non linear systems which cannot be stabilized by continuous state feedback laws.

Disadvantages:

# The main obstacles in the success of these techniques is the implementation had an important drawback that is the actuators had to cope with the high frequency control actions that could produce premature wear and tear.
