Constrained Residual Reinforcement Learning Augmentation of MRAC for Actuator-Safe Nonlinear Tracking

IEEE Access
Robust tracking under nonlinear uncertainty and actuator constraints remains challenging for model-reference adaptive control (MRAC). Deep reinforcement learning (RL) can compensate for nonlinear effects, but a standalone policy provides no inherent ...

Non parametric model reference adaptive control

, 1990
This thesis introduces a new method of adaptive control: NonParametric Model-Reference Adaptive-Control (NP-MRAC). The method relies on estimating the shape of the Finite Impulse Response (FIR) of the plant and the FIR of the controller rather than ...

Research on Independent Reference Model–Based Anti‐Interference Control for Quadrotor

Journal of Control Science and Engineering, Volume 2026, Issue 1, 2026.
The quadrotor is vulnerable to internal model parameters uncertainty and external airflow. In order to guarantee that the quadrotor tracks the reference signal quickly and smoothly under the influence of external airflow interferences and internal parameter uncertainties, an independent reference model–based anti‐interference control algorithm was ...

Lyapunov-stable discrete-time model reference adaptive control [PDF]

, 2005
Discrete-time model reference adaptive control (MRAC) is considered with both least squares and projection algorithm parameter identification. For both cases complete Lyapunov proofs are given for stability and convergence.

PID Control and Tuning Strategies for Dual‐Arm Trajectory Tracking of a Bionic Underwater Manipulator (BDA‐URM)

Journal of Robotics, Volume 2026, Issue 1, 2026.
Trajectory planning and control of bionic dual‐arm underwater robotic manipulators (BDA‐URMs) are highly challenging due to the complex interactions between the manipulator’s base, its dual arms, and the nonlinear underwater dynamics. This study proposes a novel hybrid controller to enhance trajectory tracking and control of a BDA‐URM.

A Hybrid Model Reference Adaptive and Regressive‐Form Sliding Mode Control in Discrete Domain: Robustness Under System Uncertainty

Engineering Reports, Volume 7, Issue 12, December 2025.
A novel MRASMC framework is developed, with a sliding surface derived from a regressive structure and parameters adaptively updated. An adaptive trigger condition enhances disturbance rejection without requiring complex observers or full system models.

Feed‐Forward PID‐Based Cooperative Control Strategy for Air Mass Flow and Pressure in PEMFC Systems

Energy Science &Engineering, Volume 13, Issue 11, Page 5172-5197, November 2025.
This manuscript presents an 86 kW proton exchange membrane fuel cell (PEMFC) with a feed‐forward PID control strategy, tested in an engine environment. The air mass flow and pressure changes are analyzed across three stages: loading, de‐loading, and wide range of sudden load drop. Experimental results demonstrate the control strategy's effectiveness of

Distributed fault‐tolerant control for high‐speed trains based on adaptive terminal sliding mode control

IET Intelligent Transport Systems, 2023
Here, a distributed multi‐body dynamics model of high‐speed train (HST) with actuator faults is established. Based on this detail model, a non‐singular terminal sliding mode control method is designed for HST distributed fault‐tolerant control, and the ...
