Closed-Loop Analog Control of DC Motor Velocity
University: University of California, Santa Barbara In this laboratory, students build analog circuits to implement proportional (P), integral (I), and proportional-integral (PI) control of a DC motor using NI LabVIEW. The ultimate goal is to control the DC motor so that the velocity (voltage) output VOUT is equal to a (desired) reference (voltage) input r. For this laboratory, they power LMC6484 op-amp chips using V+ = 5 V and V- = -5 V. An MC7905 negative voltage regulator is used to convert the -12 V signal from the DC power supply to a -5 V signal for the op-amp. |
