Abstract
It is well known that sliding-mode control can give good transient
performance and system robustness. However, the presence of chattering
may introduce problems to the actuators. Many chattering elimination
methods use a finite DC gain controller which leads to a finite
steady-state error. One method to ensure zero steady-state error is
using a proportional plus integral (PI) controller. This paper proposes
a fuzzy logic controller which combines a sliding-mode controller (SMC)
and a PI controller. The advantages of the SMC and the PI controller can
be combined and their disadvantages can be removed. The system stability
is proved, although there is one more state variable to be considered in
the PI subsystem. An illustrative example shows that good transient and
steady-state responses can be obtained by applying the proposed
controller
