Some problems are analyzed and generalized for micro gas turbine control system design. According to these features with multivariable, strong disturbance and time-varied parameters in gas turbine mathematical model, the single neuron controller is used to control velocity. The coupling of ancillary device control with reheater is analyzed. The theories of soft-startup＇and chopping control, battery control, inverting and merging control are introduced and the control methods are provided in terms of the operating condition requirements. It is reviewed that the performance is affected by the parameters of the designed controller. The summary and prospect of the research results are given.
