Abstract EN
This paper deals with the problems of “explosion of term,” uncertain parameter in static synchronous compensator (STATCOM) system with nonlinear time-delay.
An improved adaptive controller is proposed to enhance the transient stability of system states and reduce computational complexity of STATCOM control system.
In contrast to backstepping control scheme in high order systems, the problem of “explosion of term” is avoided by designing dynamic surface controller.
The low pass filter is included to allow a design where the model is not differentiated and thus has prevented the mathematical complexities effectively.
In addition, unlike the traditional adaptive control schemes, the certainty equivalence principle is not required for estimating the uncertain parameter by system immersion and manifold invariant (I&I) adaptive control.
A smooth function is added to ensure that the estimation error converges to zero in finite time.
The effectiveness of the proposed controller is verified by the simulations.
Compared with adaptive backstepping and proportion integration differentiation (PID), the oscillation amplitudes of transient response are reduced by nearly half, and the time of reaching steady state is shortened by at least 11%.
