This paper presents a DSP-based high performance digital automatic voltage regulator (D-AVR) for use on engine generator. The H∞ control approach is applied to the engine generator excitation control system (ECS) for the purpose of tracking a r.m.s. of sinusoidal ac voltage to a specified value. Since the implementation of the control laws has tended to the digital microprocessor, the paper extends the reformulized H∞ control to the discrete time domain. The design procedure of H∞ based ECS is explained for the purpose of constructing robust, low noise, and high performance tracking system. Simulation and experimental results show that the proposed scheme can supply a high-quality voltage power source in the presence of load disturbance.
