Simple open loop speed control system
WebbThe speed control system has the above mentioned components. The first component is the speed sensor. The speed sensor is an Infra red transmitter and receiver circuit. When a solid body passes through the u shaped slit the sensor goes to low state. Normally it … Webbparameters will be tested and observed. Open loop and closed loop speed control of the system is done and the results are tabulated which verify the effective developed drive operation. II. BLOCK DIAGRAM OF THE CONTROL SYSTEM. The block diagram of BLDC drive system is shown in Figure 1.
