The prescribed-precision position-tracking problem for permanent magnet synchronous motor servo systems subject to switchable reference signals and unknown disturbances is addressed in this article. A novel prescribed-performance control scheme is proposed to overcome the critical limitations of conventional approaches...
To fulfill the dynamic and steady-state performance requirements of permanent magnet synchronous motors (PMSMs) in speed regulation, a practical prescribed-time fuzzy adaptive control approach is investigated. First, a novel continuously differentiable time-varying scaling function is constructed, which avoids the prob...
This paper presents an event triggered adaptive fixed-time sliding mode control (ETAFTSMC) strategy for robust voltage regulation of a spacecraft DC microgrid characterized by low inertia and high sensitivity to load variations due to converter-dominated renewable energy sources integration. The proposed controller i...
This article explores an event-triggered self-learning parallel tracking control strategy for continuous-time nonlinear systems with actuator faults. To mitigate the impact of actuator faults, an enhanced performance index function is developed based on the unknown upper bound of such faults. Furthermore, an augmented...
This paper proposes an adaptive prescribed-time tracking control strategy based on the dynamic surface technique for hydraulic servo systems subject to time-varying parameters, external disturbances, and output constraints. First, a state-constrained transformation function is introduced to convert the strict output co...
