For distributed inverter voltage tracking, phase-locked loop are conventionally utilized to achieve synchronization. Its implementation requires a separate Phase-Locked Loop (PLL) with the necessary hardware, and there is still a constant offset in the reference tracking. In previous work, authors proposed a controller “matrix” based on Internal Model Principle to achieve synchronization control for...
Through the conventional Jacobian linearization, its operation has to be limited in the neighborhood of equilibrium. To address the control requirement in off-equilibrium region, optimal linearization is introduced to describe the exact dynamics at any operating point with minimal approximation error. In the illustrative example of Rotary Inverted Pendulum, a universal dynamic nonlinear model is firstly...
Network controlled system will always experience some delays in communications, and how to improve its stability is of great importance for industry applications. In this paper, one novel method of delay compensation by utilizing digital redesign is proposed. First, analog controller is designed for the delay free system, and then the delay compensation algorithm is modulated through A/D conversion...
