4 Case Study: PID-Type FLC Tuning for a DC Drive

This section is dedicated to apply the proposed metaheuristics-tuned PID-type FLC
for the variable speed control of a DC drive. All the obtained simulations results are
presented and discussed.

4.1 Plant Model Description

The considered benchmark is a 250 W electrical DC drive shown in Fig. 2 . The
machine is speed rotation is 3,000 rpm at 180 V DC armature voltage.

The motor is supplied by an AC-DC power converter. The considered electrical
DC drive can be described by the following model (Hagg
