This paper mainly focus on the research of the active tip clearance control scheme for a high pressure turbine on aircraft engine. A brief interpretation of this model is illustrated. Then a rum-time based engine control model (including steady and transient control) is added to the high pressure turbine model, the high pressure tip clearance can be simulated upon the rebuilt model. The High pressure turbine tip clearance control method is realized by bleeding the cool air from the fan to the case shroud, the objective of this paper is to derive the reasonable control plan for the Active tip clearance. © 2023 SPIE.

This paper mainly analyzes the target gear selection method when there are multiple gears on a single shift hub at the same time, and puts forward the optimal shift strategy based on different current gears. According to the speed signal sensor, accelerator pedal sensor and SOC information, the target gear of the vehicle is calculated according to the shifting rule. According to the information of the position sensor, the speed sensor and the current sensor of the gear shifting motor, the actual gear position is calculated. Based on the proposed shift strategy, the target gear position of the vehicle is optimized and the optimized target gear position is calculated. The closed-loop control platform is established by using the control strategy and 3DHT real vehicle. The proposed gear selection strategy is tested on the vehicle. The test results show that the proposed shift strategy based on different current actual gear can calculate the target gear reasonably, and the target gear is more in line with the working principle of the actuator. It can also ensure that the target gear of transmission execution is more reasonable when shifting from 1st gear to 3rd gear and 3rd gear to 1st gear, effectively reducing the impact speed on 2nd gear, optimizing the shift performance, and thus improving the service life of the 2nd gear synchronizer. © 2023 IEEE.

In order to achieve low pulsation and high precision constant flow output of a series plunger infusion pump for HPLC, a flow control method based on S-curve for series plunger infusion pumps is proposed. Firstly, motion planning is carried out for the stepper motor. Secondly, the S-curve algorithm is used to achieve smooth driving of the plunger by the stepper motor. Finally, the feasibility of the proposed method is verified through motor operation tests and flow accuracy tests. The experimental results show that this method achieves constant flow and low pulsation output of the series plunger infusion pump, and using the S-curve control algorithm, the flow stability of the infusion pump is significantly improved, with an RSD of 0.055%. © 2023 IEEE.

Permanent magnet synchronous motors (PMSM) are widely used due to their numerous benefits. It is critical to get rotor position and speed information in order to operate the motor accurately. Sensorless control techniques have emerged as a popular study area both at home and overseas. The sliding mode observer (SMO) may indirectly detect rotor position and has the benefits of easy implementation and efficient algorithms. In this study, a mathematical model for sensorless control of a PMSM is developed using SMO, vector control, and other techniques. With a surface-mounted PMSM as the study object, a mathematical model for sensorless control of PMSM is developed. PMSM's sliding mode observer model is built in the matlab/simulink environment. Experiments demonstrate that the system can track the rotor position and speed of the motor precisely and fulfill the requirements of sensorless vector control of PMSM. © 2023 IEEE.

In order to solve the problem that the thrust adjustment ability decreases and the performance is unstable when the flight conditions change which about fixed geometry or only considering the gas generator adjustable ducted rocket, we propose a multivariable adjustable ducted rocket adjustment/control method for the inlet, gas generator and tail nozzle, and design a comprehensive control scheme for ducted rocket, which can improve the engine performance through the inner loop of performance control and effectively solve the problem of continuous thrust adjustment through the outer loop of thrust control. The simulation results show that the designed control scheme can effectively improve the thrust regulation capability of the ducted rocket, and at the same time, the air-fuel ratio of the ducted rocket can be effectively controlled and the pressure of the combustion chamber can be protected, which provides design ideas for the engineering application of the ducted rocket. © 2023 IEEE.

The strain on the power grid's supply and demand balance is constantly increasing. The cost is rising as a result of the growing share of new energy generation. For such reasons, the novel load control system focusing on the exploitation and the use of flexible regulatory resources. This paper begins by conducting an in-depth analysis of the regional load control and energy regulation systems, to summarize and put forth a network architecture. Then, this paper defines a hierarchy regulation in the physical domain, flexible communication in the communication network, and multiparty coordination in the information domain. Second, this study evaluates the load control terminal's research status and suggests a system design that combines software containerization and hardware modularization. In addition, this paper presents an upgrade of the '0/1' type switch to a multifunctional load control switch to accommodate flexible device regulation. Finally, this paper reviews the research approaches to energy system management and local management over the past. Future research directions are conclusively and prospectively presented at the end to provide an overview reference for the construction of novel load control systems.
