Front wheel angle control for steering system of intelligent commercial vehicle based on model predictive control

IET Intelligent Transport Systems, Volume 17, Issue 11, Page 2268-2284, November 2023., 2023
Accurate control of front wheel angle is essential in intelligent vehicle electric‐hydraulic power steering (EHPS) system, because it has a significant impact on the safety, comfort, and reliability of vehicle steering. However, the accurate control of front wheel angle is a challenging problem due to the non‐linearity of hydraulic power in the ...

Claw‐pole magnetic levitation torque motor for 2D valve with automatic neutral adjustment

IET Electric Power Applications, Volume 17, Issue 10, Page 1285-1303, October 2023., 2023
A claw‐pole magnetic levitation torque motor with neutral regulation by means of cogging torque is proposed. A qualitative formula for the output torque is derived based on equivalent magnetic circuit, and the structural parameters of this torque motor are optimised by response surface method and NSGA‐2.

A Novel Narendra‐based adaptive anti‐disturbance control strategy for the microgrid inverters: A novel MG VSI adaptive anti‐disturbance control strategy based on Narendra theory

IET Power Electronics, Volume 16, Issue 13, Page 2261-2274, 14 October 2023., 2023
Narendra adaptive control is considered as the external‐loop and LADRC is considered as the internal‐loop to adjust controller parameters in real‐time, while the “total disturbance” can be estimated and compensated. The designed adaptive control law not only contains the augmentation error term of the system but also introduces the system state ...

Full state constrained command filtered output feedback control for the electro‐hydraulic ammunition ramming system

IET Control Theory &Applications, Volume 17, Issue 5, Page 591-604, March 2023., 2023
A state observer is designed to estimate the unmeasured states of the electro‐hydraulic ammunition ramming system. Then, command filtered technology and corresponding compensating technique of filtering errors are further applied to suppress the complexity of differential explosion in backstepping iteration.

Investigation on flat torque‐angle characteristic of torque motor based on magnetic saturation of tooth tip

IET Power Electronics, Volume 16, Issue 3, Page 357-374, 19 February 2023., 2023
Abstract The flat torque‐angle characteristic of torque motor plays a decisive role in the control quality of electro‐hydraulic servo and proportional valve. To solve the issue that the current wet‐type torque motor for two‐dimensional (2D) valve does not have flat torque‐angle characteristic, a method for adjusting the flat torque‐angle characteristic
