Abstract

The present invention discloses a DC motor control system and a switch method thereof. The DC motor control system which has a speed and position online switched consists of an inner ring, an outer ring and a switch ring. The inner ring alone controls the speed of the DC motor, the embedding combination of the inner and the outer rings control the position of the DC motor, the switch ring assuresa stable online switch from the control of the speed to the control of the position. The DC motor control system and the switch method of the present invention control not only the speed of the DC motor but also the position of the DC motor. In addition, the speed control and the position control can switch online stably and the online switch has no impact on the position to be controlled in operation. Therefore the two different controlled variables of the DC motor can be controlled anytime according to actual operation needs in production.

Description

technical field

[0001] The invention belongs to a direct current motor control system, in particular to a control system capable of controlling both the speed and the position of the direct current motor and a method for online smooth switching between the two. Background technique

[0002] At present, the known DC motor speed control or position control requires two different control systems, and the two control systems cannot be switched to each other when they are online. For the same DC motor, if the initial operation is in the speed control state and you want to switch to the position control state, you should first stop, transfer the motor and its load from the speed control system to the position control system, and then restart it. Perform position control. If the initial operation is in the position control state, it must go through the above process of stopping and restarting before it can be converted into the speed control state.

[0003] If the existing switch...
