| Abstract |
This paper reviews and develops a new approach to Fuzzy-Sliding Mode Control (FSMC) for
the robust position control of practical motor drive systems. Robustness is achieved through the
definition of a real time reference transient trajectory for the switching function of the Sliding Mode
Control (SMC); this trajectory error is the input for a fuzzy interpolation between control laws
corresponding to the boundary values of the plant parameters. The paper reviews the background of
the approach and develops a design procedure for the fuzzy interpolation to yield robust performance
for large range of parameter variations. Simulated results are presented considering the noise
constraints presented in real systems. It is well known that the transducer quality and measurement
noise ultimately limit the close loop dynamic, this paper considers this aspect of real systems and
develops a simple method to set the controller gain in order to get a robust performance during
transients and low system noise during steady state. |
