Abstract
This paper presents a practical approach to the robust speed
control of electrical drives. The approach is based on sliding mode
control (SMC), but it is shown how sampling time, system noise,
actuation limit, and antiwindup integrator reduce the control to an
online maximum-gain selection constrained by system noise. The paper
proposes a trajectory-reference compensator and fuzzy gain interpolator
to fully exploit the system actuation while avoiding chattering and
remaining within specified noise limits, only the SMC switching line
needs to be selected; the remaining control design is systematic and,
thus, should be of interest to drive engineers in industry. Experimental
results on a vector-controlled AC motor drive rig with variable-inertia
loads are presented to verify the approach
