在过程控制中，按偏差的比例（P）、积分（I）和微分（D）进行控制的PID控制器（亦称PID调节器）是应用最为广泛的一种自动控制器。(In process control, according to the percentage of deviation (P), Integral (I) and differential (D) control of PID controller (also known as PID regulators) is the most widely used of an automatic controller.)

This paper starts by analyzing the modulation requirements of a single-phase H-bridge -source inverter, and subsequently extends the analysis to cover the more complex three-phase-leg and four-phase-leg -source inverters, with carrier-based implementation reference equations derived for all the inverters. The theoretical and modulation concepts presented have been verified both in simulation and experimentally.(This paper starts by analyzing the modulation requirements of a single-phase H-bridge-source inverter, and subsequently extends the analysis to cover the more complex three-phase-leg and four-phase-leg-source inverters, with carrier-based implementation reference equations derived for all the inverters.
