This paper investigates cooperative control of a collection vehicles operating in vehicular ad hoc network (VANET) with access-constrained fading channels. To establish systematic methodology, we first formulate and solve the problem for general networked systems (NCSs) where sensors communicate controller via By introducing Markov chain model random access protocol communication modeling each channel as an independent stochastic process known probability distribution, derive new NCSs. Then,...

Due to the subsynchronous interaction between grid-side converter (GSC) of wind farms and rectifier (REC) voltage source converter-based high-voltage direct current (VSC-HVDC) transmission system, oscillations (SSOs) may occur in direct-drive with VSC-HVDC systems. Considering nonlinearities uncertainties a nonlinear SSO mitigation strategy is proposed this article based on feedback linearization theory sliding mode control (SMC). The used eliminate nonlinearities, SMC adopted improve...
Reactive power compensation requirement and large parasitic shunt-capacitor in offshore wind generation systems form the parallel-compensated grid. However, direct-drive farms connected to grid faces risk of oscillations. This article presents a unique phenomenon that participation factors (PFs) close oscillation modes are sensitive parameter perturbations. The is defined as PFs weak robustness (PFWR) its necessary conditions revealed. To deepen understanding PFWR, transfer characteristics...

We aim to stabilize the by effectively assigning channels appropriately allocating transmission powers so that energy consumption is within an budget. The role channel assignment guarantee network access for all plants when needed; mission allocation ensure desired rate successful packet each channel. These two aspects are achieved...
The low-frequency oscillation (LFO) problem of photovoltaic (PV) grid-connected systems has been a critical concern for safe operation, whereas the impact dc-side components PV plants are always ignored and single-stage plant is used.

The novel has characteristics rule linkage, which effectively improves accuracy detection environments....
This paper investigates networked control systems whose actuators communicate with the controller via a limited number of unreliable channels.
