A Robust Adaptive PID-like Controller for Quadrotor Unmanned Aerial Vehicle Systems

Aerospace
This paper introduces a stable adaptive PID-like control scheme for quadrotor Unmanned Aerial Vehicle (UAV) systems. The PID-like controller is designed to closely estimate an ideal controller to meet specific control objectives, with its gains being ...

Embedded Model Control: design separation under uncertainty

, 2014
The key signal of the Embedded Model Control (EMC) is the model error, measured minus model output, which is used by Internal Model Control and in a more efficient way by Active Disturbance Rejection Control (ADRC).

An Anti-Singularity Data-Driven-Control-Based Method for Soft Start and Multi-Machine Balance of Magnetic Couplers

Machines
The speed-regulating magnetic coupler faces challenges in mechanism modeling for constant-torque-load soft start and multi-motor power balance. Moreover, system data contain singular noise values.
