“…In recent years, the Chinese government has introduced many energy-saving and emission reduction policies to support Haier's development into intelligent high-end household appliances from the perspective of finance and technology [8] . In the Internet era, the concept of China's smart city has promoted the rise of the smart home industry, while the highly intelligent development of the traditional household appliances industry has provided a new opportunity for the diversified development of Qingdao Haier Co., Ltd. To this end, the Chinese government has formulated some policies to guide the enterprise's concept of Internet plus, let intelligence and Internet and other information technologies further penetrate into the field of traditional household appliances, and provide more development opportunities for China Haier Group's diversified channels.…”

The article mainly starts with the basic theory of modern enterprise strategy and market diversification strategy, studies the basic theoretical achievements of market diversification strategy, and expounds the research purpose and method of this chapter. With the rapid development of the current world economy and the trend of internationalization, a relatively unified and perfect global development analysis model has been gradually established for the entire global economic environment and commodity market. The further development of diversified competition strategy will also quickly become a new hot spot in the new round of market competition. Haier Group has been actively trying to develop diversification strategies since the early 1990s. The diversified development of the company’s products gradually transited to the diversified development of the company’s products. The diversified development strategy has also brought about the development trend of Haier Group’s global turnover growth and operating profit maintaining a significant growth trend year by year. Based on the diversified economic strategy and development process of Haier Group in China, this paper briefly, objectively and truly summarizes the current situation of the development process of Haier Group’s diversified business strategy in China, analyzes the experience and lessons of Haier Group’s diversified development, and constructs a SWOT analysis model.

Nowadays, AC electronic loads with energy recovery are widely used in the testing of uninterruptible power supplies and power supply equipment. To tackle the problems of control difficulty, strategy complexity, and poor dynamic performance of AC electronic load with energy recovery of the conventional control strategy, a control strategy of AC electronic load with energy recovery based on Finite Control Set Model Predictive Control (FCS-MPC) is developed. To further reduce the computation burden of the FCS-MPC, a simplified FCS-MPC with transforming the predicted variables and using sector to select expected state is proposed. Through simplified model and equivalent approximation analysis, the transfer function of the system is obtained, and the stability and robustness of the system are analyzed. The performance of the simplified FCS-MPC is compared with space vector control (SVPWM) and conventional FCS-MPC. The results show that the FCS-MPC method performs better dynamic response and this advantage is more obvious when simulating high power loads. The simplified FCS-MPC shows similar control performance to conventional FCS-MPC at less computation burden. The control performance of the system also shows better simulation results.
