Features and Specifications

• Compact system - no mechanical hassles Simplified operation
• Digital storage of transient response (step mode)
• Positive/Negative tacho generator feedback
• Position control of a 12 volt, 1 Amp dc geared PM motor ( 50 / 60 RPM )
• Calibrated dials with 10 resolution for reference and output position
• Two 3600 servo - potentiometers
• Built in step signal
• Inbuilt tacho generator with polarity reverse switch
• Calibrated forward path gain 3 to 10 in steps
• Calibrated tacho constant 0.2 to 1 in steps
• The motor unit is housed in a separate cabinet with transparent Cover for easy viewing.
• Interconnection with the main unit is through a standard 9-pin D-type connector. All power supplies and step input signal are internally provided. In addition a 3½ digit DVM is available on the panel for the measurement of various signals. A good quality measuring CRO is the only accessory that would be required.

                : 2 kg motor unit (approx.)

List of Experiments

• Operation of the position control system for different values of the forward gain to angular position commands(effect of forward path gain in steady state error)
• Step response studies for various values of forward gain(to analyse the transient)
• Study of the effect of velocity feedback on the transient and steady state performance of the system as well as its stability(Effect of velocity feedback upon transient response)
