Traditional construction machinery has the disadvantages of low energy efficiency and poor emissions, which do not meet the requirements of environmentally friendly industrial development. Electric construction machinery has attracted more and more attention because of its advantages of zero emissions and high energy efficiency, which are considered to be important factors in the future development of construction machinery. Preliminary attempts to introduce electric motors into construction machinery usually only adopt the motor for simulating the working mode of the engine, with it providing power for the system. Because the output power of the motor needs to be matched with the actual load through the transmission of the hydraulic torque converter, it is difficult to maximize the advantages of high energy efficiency for the electric drive. This paper studied the direct drive technology within electric construction machinery and presents a model reference adaptive algorithm (MRAA) based on maximum torque per ampere (MTPA)-vector control of an internal permanent magnet synchronous motor (IPMSM). The reference motor model was established, and the real-time dynamic reference value of the motor was obtained based on a model with the motor voltage and current as inputs. Simulations based on MATLAB/Simulink verified the feasibility of this control method. The results indicate that the MRAA can identify the motor flux linkage value and the d-q axis inductance within 50 ms in real time, with the error controlled within 2%. Additionally, when the motor operates at low speed, compared with the traditional MTPA algorithm under fixed-parameter control, the starting torque ripple of the IPMSM control method based on reference model adaptation was reduced to 23.8%, which proves that the MRAA can achieve good low-speed response characteristics and stability.

As human beings are advancing in technology the demand for power is drastically increasing. To cope up with these increasing energy demands renewable energy was included in the power system in the early 20th century. A rise in the usage of renewable energy sources for power production has been motivated by concerns about global climate change and air pollution. These new sources of renewable energy are in high demand for creating microgrids that give energy independence to remote populations. If these microgrids are to be successful, they must be able to function in either an isolated or a linked state. These standards are very difficult to meet. Small and medium power networks in isolated mode are, in fact, very susceptible to variations in consumer power demand and changes in the power generated by generators. Two independently regulated solar power sources, power storage, as well as a resistive load are all included in this study’s distributed photovoltaic (DP) system design. Sliding mode controllers are used to regulate the cascaded DC-DC boost converters on each PV panel. A DSM-PI controller and a PI-sliding mode controller will be used to regulate power converters that connect the source and the common DC bus. Using numerical simulations, this research compares the MPPT algorithm’s performance in each operating state to the accuracy of the supervisory controller. The DSM-PI controller is more efficient as compared to conventional sliding mode controller. All the results are generated using MATLAB Simulink software.

The traditional loader drive system is based on the hydraulic torque converter as the key component, and its gear is shifted through the coordination of the clutch and gearbox, which greatly increases power loss and operator fatigue. To address the above problem, a variable-structure hydrostatic drive system is proposed. This system adopts a closed-loop design and adjusts the displacement of the pump and dual motors to follow the throttle opening of the vehicle, achieving automatic gear shifting and smooth speed regulation. It can also automatically change the system structure according to the vehicle’s speed, meeting the vehicle’s demand for rapid switching output of high torque and high speed. At the same time, in the displacement matching control process, an adaptive sliding mode control scheme based on radial basis function neural network compensation is proposed. This scheme designs an adaptive hyperparameter update strategy according to the characteristics of the system to effectively compensate for changes in uncertain factors. Experimental results show that, compared to traditional drive systems, this system has the characteristics of simple operation, smooth speed regulation, and high fuel economy.
