Description

technical field

[0001] The invention relates to a speed regulating device of a direct current motor, in particular to a speed regulating device of a direct current motor which realizes speed control by using energy balance relationship. Background technique

[0002] The DC speed control system is widely used in various industries due to its advantages of good speed control characteristics and large starting torque. Existing DC speed control systems mostly use PID (proportional, integral, differential) controllers to control and adjust the motor speed. Although the PID controller is simple in design and easy to implement, it also has narrow bandwidth and control time lag. Problems limit the performance improvement of the speed control system. Contents of the invention
