Cascade Speed Control Of Dc Motor
Abstract: This paper presents a MATLAB aided Cascade designed controller to control and monitor the DC motor speed.
First, design the driver circuit of the DC motor and use the microcontroller PIC16F877A to collect the feedback signals from
the current sensor and optical encoder. The measured speed and current are serially transmitted to PC using RS232. By the
MATLAB aided cascade controller, where inner loop is the current loop and outer loop is the speed loop, the parameters are
adjusted to control the motor speed. The PC displays the measured speed and required speed.
