Description

technical field [0001] The invention relates to a diesel engine speed control device and a control method thereof, belonging to the field of digital speed control, in particular to a diesel engine digital speed control device and a control method thereof. Background technique [0002] At present, diesel generators usually use analog speed control devices, and the analog speed controllers mainly have the following problems: 1. Due to the use of many separate components, the power consumption is large and the reliability is reduced; 2. In the traditional In the analog speed controller, the potentiometer knob is usually used to set the speed. Therefore, it will eventually affect the control accuracy of the speed, and it is difficult to achieve precise speed control; 3. The control method with fixed PID parameters is usually used. Under different operating intervals and operating states, variable parameter control cannot be realized. Contents of the invention [0003] The tec...
