Position actuator with small DC motor, torque 1 Nm, range 210 grad, using dynamic superposition of vibrations for decreasing of friction effect and clearances in gear box. and Polohový servomechanismus s malým stejnosměrným motorkem, točivý moment 1 Nm, rozsah 210 grad, využívající dynamické superposice vibrací pro potlačení vlivu tření a vůlí v převodovce.
The proposed article deals with uncertain description of permanent-magnet DC motor Maxon RE 35 via parametric uncertainty and H-infinity controller design. There was analyzed influence of uncertainties of the particular motor parameters on the model behavior. Consequently there was designed an H-infinity controller via Matlab functions. The behavior of the obtained controller was analyzed on the step responses and course tracking of the closed loop with the nominal system and the system with perturbed parameters. and Obsahuje seznam literatury
