This paper investigates the proportional-integral-derivative (PID) control of positive systems in discrete-time case. First, a tuning parameter is introduced to construct framework systems. The problem thus transformed into synthesis with time-delay. By virtue matrix decomposition approach, gain matrices controller are designed. Using co-positive Lyapunov functions and linear programming, posit...

In-silico control of complex stochastic biological systems is a promising area cybergenetics, which provides enabling theoretical and practical tools for the real-time living cells with digital computers. We demonstrate here that simple proportional-integral laws can be used to both mean variance expression product gene network. Extensions more general unimolecular networks, networks input dela...

Steer-by-wire is the electrical steering systems on vehicles that are expected with the development of an optimal control system can improve the dynamic performance of the vehicle. This paper aims to optimize the control systems, namely Fuzzy Logic Control (FLC) and the Proportional, Integral and Derivative (PID) control on the vehicle steering system using Imperialist Competitive Algorithm (IC...

The article focuses on the issues of Load Frequency Control (LFC) under non-linear strategies in multi source multi area hydro thermal system. On practical perspective dead band, boiler dynamics, reheat steam turbine along with hydro turbine operating under two different area capacities are considered in the system. When subjected to random load variations in both the areas, the system exhibits...

Integration of the PV into the electrical grid needs power electronic interface. This power electronic interface should have some key features and should come up with grid codes. One of the important criteria is the quality and harmonic contents of the current being injected to the grid. High-order harmonics of the grid current should be very limited (lower than 0.3% of the fundamental current)...
