چکیده
The tracking of a given voltage in the traditional double closed-loop proportional integral control current power grid simulator has problems such as static difference, delay and oscillation. It is proposed that outer loop inner inverter side adopt quasi-proportional resonance respectively, topology adopts cascaded modular design to establish single-phase model. Compared with proportional-integral control, it verified proportional-integral-quasi-proportional resonant controller can effectively improve system’s ability track command stability output voltage.

Proportional-integral extremum-seeking control
This paper proposes a proportional-integral extremum-seeking control technique. The technique is a generalization of the standard perturbation based techniques that provides fast transient performance of the closed-loop system to the optimum equilibrium of a measured objective function. The main contribution is that the formal development of this technique does not require the need for a time-s...

This paper presents the design of controller based on proportional resonant strategy for single-phase grid connected inverter. The control design is carried out using Sisotool, which is provided in Matlab. By using this tool, users can examine the effects of changing the gain control values to system's transient response and stability, simultaneously. Hence, simplify and speed up the control de...
متن کاملA Chaos-Based Communication Scheme Using Proportional and Proportional-Integral Observers
In this paper, we propose a new chaos-based communication scheme using the observers. The novelty lies in the masking procedure that is employed to hide the confidential information using the chaotic oscillator. We use a combination of the addition and inclusion methods to mask the information. The performance of two observers, the proportional observer (P-observer) and the proportional integra...
متن کاملDesign of Proportional Integral Adaptive Observers
Adaptive observers were first introduced by Carroll and Lindorff in [1], and later on modified by Kudva and Narendra in [2]. For a more detailed analysis and design of adaptive systems see [3], [4], [5]. In many applications where the parameters are unknown and states are not accessible, adaptive observer appears to be a valuable method in estimation of both parameters and states of the system....
متن کاملA proportional integral extremum-seeking control approach
This paper proposes an alternative extremum seeking control design technique for the solution of real-time optimization control problems. The technique considers a proportionalintegral approach that avoids the need for a time-scale separation in the formulation of the ESC. It is assumed that the equations describing the dynamics of the nonlinear system and the cost function to be minimized are ...
