DC Servo

The experiments are carried using training panels in panel frames.

Objectives

• Experiment set-up and wiring according to circuit diagrams
• Working with closed-loop control systems
• Optimisation of servo systems
• Use of computer-controlled measuring interfaces

Function

The equipment set incorporates student experiments which can be carried out in a laboratory safely using safety extra-low voltage. Experiment instructions are contained in a manual in either printed or digital form.

The target group is made up of commercial apprentices and students of power engineering and mechatronics. The course offers introductory experiments at an intermediate level for vocational schools and colleges.

Topics

• Recording of step response
• Determination of K_pcrit und T_crit and calculation of settings for P, PI and PID systems
• Closed-loop step response for P-controller
• Correction for K_p with respect to integral-action systems
• Step response for PID-controller
• Determination of limiting frequency of servos
• Use of measurement interfaces
