Linear-Extended-State-Observer Based Pinning Control of Nonlinear Multi-Robots System
IEEE Access, 2020 In this paper, the pinning control problem of nonlinear multi-robots system (MRS) is investigated. By introducing Linear-Extended-State-Observer (LESO) approach, a LESO based pinning control algorithm is proposed for the multi-robots system with non ...

Sensorless Control of Dual Three-Phase IPMSM Based on Frequency Adaptive Linear Extended State Observer [PDF]
, 2023 The sensorless control of interior permanent magnet synchronous motor (IPMSM) based on the conventional linear extended state observer (LESO) does not have sufficient capability to eliminate the steady-state position estimation error. To solve this issue,

Current-cycle iterative learning control for high-precision position tracking of piezoelectric actuator system via active disturbance rejection control for hysteresis compensation [PDF]
, 2019 As a typical smart structure, piezoelectric actuator (PEA) is an essential constituent component in piezoelectric-driven positioning stages. Nevertheless, the positioning precision is severely degraded by its innate rate-dependent hysteretic nonlinearity.
