Online Parameter Identification
Process of continuously estimating the parameters of a dynamic model during its operation, allowing real-time adjustment of the controller.
Adaptation Law
Mathematical algorithm defining how the controller parameters evolve based on tracking error and system measurements.
Lyapunov Stability
Analysis method ensuring that the adaptive system converges to a stable equilibrium state despite parameter variations.
Robust Adaptive Control
Control technique combining parameter adaptation and robustness to maintain stability in the face of unstructured uncertainties.
Adaptive Neurocontrol
Use of artificial neural networks to approximate nonlinear dynamics and adapt control in real time.
Time-Varying Parameter System
Model whose parameters change over time or according to operational conditions, requiring adaptive control.
Recursive Estimation
Parameter estimation method that continuously updates estimates using new measurements without recalculating the entire history.
Adaptation Gain
Adjustable parameter controlling the convergence speed of the adaptation algorithm, balancing speed and stability.
Reference Model
Ideal dynamic system defining desired performance, used as a target for model reference adaptive control.
Adaptive Predictive Control
Strategy optimizing future actions over a sliding horizon while adapting the predictive model in real time.
Adaptive Observer
State estimator that simultaneously adapts its parameters to reconstruct unmeasurable internal variables of the system.
Disturbance Compensation
Adaptive technique identifying and actively counteracting external disturbances to maintain nominal performance.
Persistence of Excitation
Mathematical condition ensuring that input signals contain sufficient information to correctly identify parameters.
Lyapunov Candidate Function
Energy function used to prove the stability of adaptive systems by analyzing its monotonic decay.
Direct and Indirect Adaptation
Classification distinguishing direct controller adaptation from adaptation via model estimation (indirect).
