In this paper, a novel approach for two-loop control of the DC-DC Ćuk converter in discontinuousconduction mode is presented using a sliding mode controller. The proposed controller can regulatethe output of the converter in a wide range of input voltage and load resistance. Controllerparameters are selected using PSO algorithms. In order to verify the accuracy and efficiency of thedeveloped sl...

This paper presents a new optimization algorithm to design an optimal proportional, integral, derivative (PID) controller in hydro-turbine generator governor for damping output frequency oscillations. In this research, we utilize a stochastic and optimal based PID controller to control frequency-response of the hydro turbine. The proposed algorithm is employed to design an optimal PID controlle...

This paper addresses the design of a nonlinear time-invariant, dynamic state feedback receding horizon controller, which guarantees constraint satisfaction, robust stability and offset-free control of constrained, linear time-invariant systems in the presence of time-varying setpoints and unmeasured, persistent, additive disturbances. First, this objective is obtained by designing a dynamic, li...

In this paper, the Unified Power Flow Controller (UPFC) is enhanced with a Chaotic Particle Swarm Optimization (CPSO) Damping Controller in order to mitigate the Low Frequency Oscillations (LFO) in a Single Machine Infinite Bus (SMIB) power system. The designed damping controller is an optimized lead-lag controller, which extracts the speed deviation of the generator rotor and generates the out...

Synopsis. Brood weight and number of eggs per brood are primarily determined by female body size in brachyuran crabs. Brood weight exhib? its an isometric relationship spanning more than four orders of magnitude in body weight among 33 non-pinnotherid species, with brood size being constrained to about 10% of female body weight by the space available for yolk accumulation within the cephalothor...

This paper applies integrated system modeling and control design process to a continuously variable valve timing (VVT) actuator system that has different control input and cam position feedback sample rates. Due to high cam shaft torque disturbance and high actuator open-loop gain, it is also difficult to maintain the cam phase at the desired constant level with an open-loop controller for syst...

In this work, one improved symmetric time-variant logarithmic barrier, Lyapunov function (BLF), is developed for the first time to handle state constraint problem of nonlinear systems. It universal in sense that barrier a general can be used not only systems with constrained requirements but also without requirements, altering designed controller. First all, n-link robotic system transformed in...

This paper investigates the problem of robust output regulation control with prospected transient property for strict feedback systems. By employing internal model principle, a can be transformed to stabilization new constraint. Then, by constructing speed function and adopting barrier Lyapunov technique, dynamic controller designed not only drive error closed-loop system entering into prescrib...

this paper works on the concept of flatness and its practical application for the design of an optimal transient controller in a synchronous machine. the feedback linearization scheme of interest requires the generation of a flat output from which the feedback control law can easily be designed. thus the computation of the flat output for reduced order model of the synchronous machine with simp...
