Environment parameters are the main factors affecting the growth and development of Agaricus bisporus.Because of the requirements of environmental conditions for high-efficiency industrialized production of Agaricus bisporus,equipments for environment control were developed.Based on the variable operating equipment,a multi-factor fuzzy controller was designed to realize the comprehensive control of ambient temperature,humidity,CO2 concentration,and the temperature and moisture of the compost.The test results showed that the temperature control error was less than±0.5°C and the response speed was more than 0.5°C/h;The control error of ambient humidity was less than±2%RH,and the response speed was more than 9%RH per hour;The moistures at different points in compost ranged from 50%to 70%with a standard deviation of 4.04.The control accuracy of environmental CO2 concentration was within 200μmol/mol.The overall performance of the control system was stable and reliable,which could meet the requirements of environment factors for the growth of Agaricus bisporus.The system can provide technical support and reference for the automatic and precise control of the environment during the industrialized production of Agaricus bisporus.

Recent Progress in Reinforcement Learning and Adaptive Dynamic Programming for Advanced Control Applications

Reinforcement learning(RL) has roots in dynamic programming and it is called adaptive/approximate dynamic programming(ADP) within the control community. This paper reviews recent developments in ADP along with RL and its applications to various advanced control fields. First, the background of the development of ADP is described, emphasizing the significance of regulation and tracking control problems. Some effective offline and online algorithms for ADP/adaptive critic control are displayed, where the main results towards discrete-time systems and continuous-time systems are surveyed, respectively.Then, the research progress on adaptive critic control based on the event-triggered framework and under uncertain environment is discussed, respectively, where event-based design, robust stabilization, and game design are reviewed. Moreover, the extensions of ADP for addressing control problems under complex environment attract enormous attention. The ADP architecture is revisited under the perspective of data-driven and RL frameworks,showing how they promote ADP formulation significantly.Finally, several typical control applications with respect to RL and ADP are summarized, particularly in the fields of wastewater treatment processes and power systems, followed by some general prospects for future research. Overall, the comprehensive survey on ADP and RL for advanced control applications has d emonstrated its remarkable potential within the artificial intelligence era. In addition, it also plays a vital role in promoting environmental protection and industrial intelligence.
