首先说明ADS1158命令读写模式，然后解析命令含义及配置顺序等。(First, the ADS1158 command read and write mode, and then parse the command meaning and configuration order and so on.)

真空机组先启动SK-30水环真空泵带压力降到6.5 KPa（此时真空机组的抽速是SK-30的抽速）启动ZJP-1200（此时真空机组的抽速是ZJP-1200抽速）待压力降到4 KPa启动ZJP2500（此时真空机组的抽速是ZJP-2500抽速）待压力降到1kpa时最后启动ZJP5000（此时真空机组的抽速是ZJP-5000抽速）到100Pa达到使用真空度时时就可以关闭机组(Vacuum unit first start SK-30 water ring vacuum pump with pressure drops below 6.5 KPa (pumping speed of the vacuum unit at this time is SK-30 pumping speed) start ZJP-1200 (pumping speed of the vacuum unit at this time is ZJP-1200 pumping speed ) until pressure drops below 4 KPa start ZJP2500 (pumping speed of the vacuum unit at this time is ZJP-2500 pumping speed) until the last start when pressure drops 1kpa ZJP5000 (pumping speed of the vacuum unit at this time is ZJP-5000 pumping speed) to 100Pa achieved using vacuum unit can be closed from time to time)

The performance of controlled complex dynamic systems inevitably suffers from various disturbances and uncertainties. Moreover, different faults (sensor and actuator faults for example) can occur. Sliding mode based observers have shown high performance for states and parameter estimation robustness with regards to measurement noise even in the presence of unknown inputs. The aim of this Special Issue is to summarize and provide the recent advances in sliding mode based disturbance and parameter estimation, faults detection (DPEFD) and their attenuation. The proposed Special Issue will facilitate faster uptake of advanced sliding mode based DPEFD technologies, as well as address new challenges arising from upcoming complex control systems, and generate new theories and methodologies.

用单片机控制输出电压，MCU控制输出，我没有用过，大家可以参考(MCU control the output voltage, MCU control output, I have not used, we can refer to)
