Embodiment Construction
[0019] combine Figure 3 to Figure 6 Describe this embodiment, an effective method for suppressing the zero drift of single-rod tracking, which is implemented by the following steps:
[0020] 1. Acquisition working method; the working method includes index tracking method, visible TV tracking method or infrared TV tracking method;
[0021] 2. Determine whether it is a single-lever work mode, if not, enter other tracking methods, and if so, enter the single-lever workflow;
[0022] 3. If it enters the single-lever workflow, judge whether the single-lever enters the dead zone;
[0023] 4. If you do not enter the single-lever dead zone range, continue to work in the single-lever mode. If you enter the single-lever dead zone range, collect the current encoder value, and assign the single-lever controller value to the digital controller, and switch the working mode to Numeric fixed-point working mode;
[0024] 5. In the fixed-point working mode, judge whether the single pole exc...
