研究目的
To study the problem of stabilization control for a class of continuous-time fractional systems subject to external constant disturbances based on a disturbance observer.
研究成果
The paper concludes that the developed fractional disturbance observer-based control scheme can effectively stabilize continuous-time fractional linear systems in the presence of unknown constant disturbances, ensuring the closed-loop system states are positive and asymptotically stable. Numerical simulations validate the effectiveness of the proposed method.
研究不足
The study focuses on continuous-time fractional systems with external constant disturbances and assumes the matrix B is invertible. The external disturbance is assumed to be a nonnegative constant vector and bounded. The initial conditions must satisfy certain nonnegativity constraints.
