lab (velocity control system with DC MOTOR) Please I need your help I want you write introduction for this subject
2. VELOCITY CONTROL SYSTEM with DC MOTOR When operating a servo motor in a control system, we start with a command value, eg, a particular speed which you want the motor to maintain. The actual speed of the motor is called the feedback (or actual) value. The feedback value sig- nal comes from the encoder, which is mounted on the motor shaft. Equipment Base unit Servo regulator SRI Velocity control module SR2 Support plate DC motor without gear Universal instrument The brain of the system is the servo regulator, which collects the feedback and command values and tries to keep the differences between these signals to a minimum. We are now going to study how the servo regulator in a velocity control system has to be set and how its parameters P, I, and D affect the rapidity, accuracy and stability of the system.
