The purpose of<br />the problem is to control the setting value of the thrust disk to reach the desired position. First, the mathematical model of non-laminated<br />active magnetic thrust bearings in the form of a fractional order derivative component is introduced. To obtain the stability of the control<br />object, the Lyapunov function is selected to have a positive value, and the control current is chosen so that the fractional derivative of the<br />Lyapunov function is negative to verify the performance of the non-laminated active magnetic thrust bearings using backstepping control<br />technique, a simulation structure was performed on MatlabSimulink software. The results show that non-laminated active magnetic thrust<br />bearings stabilize the actual state variable values and reach the desired set value in a very short time.</span> </p>}, number={1}, journal={Measurement, Control, and Automation}, author={Le Ngoc Hoi and Nguyen Quang Dich and Le Duc Thinh and Lam, Nguyen Tung}, year={2023}, month={Apr.}, pages={29-35} }
