Non linear controllers applied to a DC-DC boost converter

Variable structure control for an isolated boost converter used in fuel cell applications

“…In the linear peak current control (LPCM) [10] peak switching current has to be sensed and therefore the sensing devices needed are more. In non-linear carrier current control (NLC) [11,12] three reset integrators are needed to generate the carrier waveform. The NLC controlled converter results in distorted input current waveform in discontinuous conduction mode of operation.…”

On Control of a Boost DC-DC Power Converter under Constrained Input

“…In order to provide a degree of robustness to compensate uncertainties in the load, supply voltage, and unmodeled disturbances, many control algorithms have been devised to achieve voltage output regulation; see, for example, [9][10][11][12]. More recently, the work in [13] presented a comparison of nonlinear controllers for the DC-DC boost power converter. In [14], the problem of output feedback regulation via Lyapunov's theory was addressed.…”

Experimental Implementation of New Sliding Mode Control Law applied To a DC–DC Boost Converter

“…Some of the existing solutions are based on the high order sliding mode with super twisting algorithm [17][18][19][20][21]. However these combinations give rise to controllers which are unable to deal with the nonminimum phase behavior of the boost converter [26]. In [23], the authors combined the SMC technique with a PI controller while a combination with a backstepping controller was preferred in [24] and a fuzzy controller in [25].…”

“…It is proved that an SMC with a nonlinear sliding surface is able to reduce the tracking error [32] and give high performance, high robustness, a good transient and effective disturbance rejection [33][34][35][36]. In [26,37], the authors showed through computer simulations that the chattering phenomenon is practically eliminated and the nonminimum phase problem is solved by an SMC based on a nonlinear surface slightly different from the SMCNL developed in this paper. Indeed, in [37], computer simulations were presented while the present work aims mainly at implementing the two control laws based, respectively, on a nonlinear and a linear sliding surface and validate the obtained result.…”
