We previously proposed a speech dereverberation method based on the modulation transfer function (MTF). This method consists of power envelope restoration and carrier regeneration processes, and reduces both the loss due to degraded power envelopes and the loss of speech intelligibility. In the power envelope restoration, however, whether adaptive time-frequency division provides the best repre...

This paper develops an improved distributed finite-time control algorithm for multiagent-based ac microgrids with battery energy storage systems (BESSs) utilizing a low-width communication network. The proposed can simultaneously coordinate BESSs to eliminate any deviation from the nominal frequency as well solving state of charge (SoC) balancing problem. stability is established using Lyapunov...

Many isolated small power systems are powered by diesel generators, which results in greater operating costs than interconnected large grids. It is therefore desirable to integrate renewable energy sources such as wind power into these small grids. However, due to the fluctuating power generation from renewable energy sources, frequency deviations of power systems become problematic. Distribute...

The new control paradigm Internet of Things (IoT) in intralogistics propagates highly modular and flexible decentralized control systems based on agent technology and radio-frequency identification (RFID). The productive application of such systems demands the fulfillment of several requirements, which exist in the industrial reality of the facility logistics. The real-time requirements in dece...

Abstract—Power System Stabilizer (PSS) are added to excitation system to enhance the damping of electric power system during low frequency oscillations. Design of decentralized PSS for 4 machines with 10 buses using fast output sampling feedback is proposed. The nonlinear model of multi-machine system is linearized and linear state space model is obtained. A stabilizing state feedback gain is o...

A novel design of a robust decentralized load frequency control (LFC) algorithm is proposed for an inter-connected three-area power system, for the purpose of regulating area control error (ACE) in the presence of system uncertainties and external disturbances. The design is based on the concept of active disturbance rejection control (ADRC). Estimating and mitigating the total effect of variou...

This paper presents a novel approach for designing a decentralized controller for load frequency control of interconnected power areas. The proposed fuzzy logic load frequency controller (FLFC) has been designed to improve the dynamic performance of the frequency and tie line power under a sudden load change in the power areas. The effect of generation rate constraint (GRC) for both areas has b...

The paper proposes a new frequency domain approach to the design of robust decentralized controllers (DC) for continuous-time systems described by a set of transfer function matrices. To guarantee the nominal stability and the prespecified nominal performance, the recently developed DC design technique (Kozáková and Veselý, 2003) has been applied, adapted so as to guarantee the robust M-∆  str...
