In order to further improve control accuracy, response speed, and the steady performance of the electric power steering system, this article based on dynamics model of the electric power steering system, designed a new assistance control strategy, advanced a control policy combining fuzzy control with PID control, and established a simulation model of EPS. This paper simulated the fuzzy self-tuning PID controller by Matlab, and compared with conventional PID control. Simulation results showed that the control method improves the system to control speed and performance, has good control performance.

With the development of distributed renewable energy and the energy Internet, the cost of distributed energy participating in traditional power transactions continues to rise, and there is an urgent need for more reasonable transaction mechanisms and efficient information technology to improve the efficiency of distributed energy transactions. The characteristics of blockchain technology are in line with the transaction needs of distributed renewable energy, and it has development potential in energy transactions. Based on blockchain technology, this paper designs a source-load transaction mechanism in which the virtual energy medium is the equivalent of the intermediary. This mechanism can avoid the problem of credit asymmetry between buyers and sellers. We design from three aspects: transaction, payment, and settlement, and verify the actual application. The results show the feasibility and effectiveness of the transaction, provide a new way for multi-frequency and small transaction volume of new energy transactions, and provide new solutions for the consumption of new energy such as photovoltaics and wind power.
