Designing the Output Feedback LQG Controller Applying for Electrical Drive System

Electric drive systems have been widely used and developed in the industry. With the development of science and technology, these systems are applied strongly in clean technologies such as food technology, biotechnology or chemical pumping and blood pumping system in the artificial heart.New control methods are increasingly being studied and applied in place of conventional control methods with the aim of improving system quality.Today, with advanced sensor technology that enables to measure physical signals, the output feedback controller called Linear Quadratic Gaussian–LQG is useful for evaluating system dynamics based on the output signals.The application of this designing method with some electric drive systems will attract more research interests.
