Motor Speed Control Bandwidth at Pearl Brandon blog

Motor Speed Control Bandwidth. In this scenario, the current loop bandwidth should be 5 to 10. Machines that need fast move and settle times, require higher bandwidths. High performance motor drives in servo control applications are expected to provide high precision and high bandwidth control of current,. In an effort to improve inner loop bandwidth, designers have boosted pwm carrier frequency to 30 khz and above. In these systems, pi controllers typically limit current loop bandwidth to about 10% of the pwm carrier frequency, which typically operates at around 10 khz. When a motion command is received, high bandwidth is key to a fast servo system response. Higher bandwidth leads to complexity and power management issues. Higher loop gain always results in higher bandwidth. Loop gain can be increased or This application report helps to evaluate fast current loop (fcl) for high bandwidth current loop control of pm servo drives and its frequency. The control bandwidth of fast current loop and the operating speed range of motor are experimentally verified. For servo control loops, the inner loop should have a bandwidth that is 5 to 10 times faster than the outer loop. Servo bandwidth is a direct function of loop gain, which includes gains from the plant, the sensor, the motor, the motor drive and the control gain. This design guide documents the test.
