Demonstration & Results

24
• Close-loop system may become
unstable under certain condition
• Instability caused by delays may
damage equipment and reduce
precision
PHIL Stability Analysis
• Stability depends on:
• Ratio of load power over short-circuit power of
the feeder
• Type of load
• Damping of source impedance
• Power amplifier bandwidth
• Simulator’s sampling frequency
• Use of current feedback filter
PHIL simulation equivalent circuit

25
• Instability caused by the interaction of:
• Lsource (linear gain with a phase of −𝜋
2)
• L//R filter and voltage amplifier
(Limit gain, add phase lag)
• IO time delay (add linear phase lag)
• Type of load (Higher power, higher gain)
• Resistive (No phase effect)
• Inductive (Reduce Lsource phase & gain)
• Capacitive (Increase Lsource phase & gain)
• Current feedback filter (Limit gain at fc)

• Bode Diagram
• Stability becomes gain dependent
when phase reaches 0
• Maximum stable load (ga𝑖𝑛 ≤ 1),
determines max load power
• Lower sample time increases the
simulation stability and accuracy
• Cut all frequencies beyond a phase
gain of -π
