This paper presents a particle swarmoptimization (PSO) based algorithm to perform congestionmanagement by properplacement and sizing of one unified power flow controller (UPFC). The proposed approach makes use of the PSOalgorithm to allocate the near-optimal GenCos as well as the optimal location and size of UPFC whereas the Newton–Raphson solution minimizes the mismatch of the power flow equat...

A neural network robust controller (NNRC) to enhance the robustness of the conventional feedback controller is proposed in this paper. The control system consists of an optimal conventional feedback controller and a neural network robust controller in parallel to the controlled system. The optimal controller is used to guarantee the stability of the whole control system and present the optimal ...

in this article, vehicle cornering stability and brake stabilization via bifurcation analysis has been investigated. in order to extract the governing equations of motion, a nonlinear four-wheeled vehicle model with two degrees of freedom has been developed. using the continuation software package matcont a stability analysis based on phase plane analysis and bifurcation of equilibrium is perfo...

In this work, a quasi-time-optimal, nonlinear state-feedback control for the torsional torque of a two-mass system (TMS) is presented. The control scheme considers constraints in the stator voltage and currents of the driving machine: a permanent magnet synchronous motor (PMSM). Its design is based on results of the more general framework of optimal control and its implementation constitutes an...

Abstract In the absence of drugs and vaccines, policymakers use non-pharmaceutical interventions such as social distancing to decrease rates disease-causing contact, with aim reducing or delaying epidemic peak. These measures carry economic costs, so societies may be unable maintain them for more than a short period time. Intervention policy design often relies on numerical simulations models, ...

An optimal controller for auxiliary heating of passive solar buildings and commercial buildings with high internal gains is tested in simulation. Some of the most restrictive simplifications that were used in previous studies of that controller (Kummert et al., 2001) are lifted: the controller is applied to a multizone building, and a detailed model is used for the HVAC system. The model-based ...

In cruise control systems, the performance of the controller is important. Hence, in order to have accurate results, the nonlinear behavior of a vehicle model should also be considered. In this article, a vehicle with a nonlinear model is controlled by using a nonlinear method. The nonlinear term of the model is the generated torque of engine, which is a polynomial equation. In addition, feedba...
