The problem of multivariable controller synthesis for a turbogenerator is considered. Using the feedback linearization approach for multi‐input non‐linear systems, the existence of a linearizing state feedback for the improved reduced‐order model of a turbogenerator is proved and the simplest form of this feedback is derived. Application of the obtained non‐linear controller to the multivariable control of a turbogenerator provides very good results not only for the reduced‐order model but also for the ‘exact’ (Park's) model of a turbogenerator. Simulations of fault and post‐fault conditions in the obtained nonlinear control system confirm its superiority over a system with a voltage regulator and power system stabilizer.
