In order to quantitatively describe the range of load change that the system can bear
a controller for inverter base on H∞ control method is designed in this paper.The error between mathematical model and practical object ofinverter is fully considered in the design.Using the output multiplicative perturbation to describe the uncertainty model caused by the load changing
sinusoidal signal is used as designing and tracking target.Simulation results show that the controller can endow the SPWM inverter with go...
