- Model reference composite learning control without persistency of excitation (2016, methodology): “(7) Let an adaptive law of �̂ be as follows: �̇̂ = ��(�T��Φ(�)) (8) where � ∈ R+ is a learning rate, and �( ∙ ) is a projection operator in the following form [3]: �( ∙ ) = ∙ if ∥ �̂ ∥ < �� or ∥ �̂ ∥ = �� & �̂T ∙ ≤ 0 ∙ − �̂�̂T ∙/ ∥ �̂ ∥2, otherwise .”
- Adaptive asymptotic tracking control of uncertain nonlinear systems with input quantization and actuator faults (2016, methodology): “To suppress this effect, we use the adaptive σ -modification method introduced in Ioannou and Sun (1996), Li and Tong (2015), Liu and Tong (2014, 2016), Li and Yang (2016a,b), and Zhang et al. (2015). As we will see from the simulation results in the next section, decreasing the values of σ might re”
- Distributed Consensus of Second-Order Multi-Agent Systems With Heterogeneous Unknown Inertias and Control Gains Under a Directed Graph (2016, methodology): “By introducing an adaptive σmodification scheme, the consensus error converges to zero asymptotically, unlike the general boundedness results for traditional σ-modification [25].”
- A Family of Gradient Descent Grid Frequency Estimators for the SOGI Filter (2018, methodology): “The gradient descent is the simplest method for optimizing an objective function or obtaining an estimate of a time-varying parameter, so suitable for being implemented in a digital processor with a small computational load [40], [41].”
