Book excerpt: Sliding-Mode Control (SMC) has several benefits over traditional Proportional-Integral-Differential (PID) control in terms of fast transient response, robustness to parameter and component variations, and low sensitivity to loop disturbances. An All-Digital Sliding-Mode (ADSM) controlled DC-DC converter, utilizing single-bit oversampled frequency domain digitizers is proposed. In the proposed approach, feedback and reference digitizing Analog-to-Digital Converters (ADC) are based on a single-bit, first order Sigma-Delta frequency to digital converter, running at 32MHz over-sampling rate. The ADSM regulator achieves 1% settling time in less than 5uSec for a load variation of 600mA. The sliding-mode controller utilizes a high-bandwidth hysteretic differentiator and an integrator to perform the sliding control law in digital domain. The proposed approach overcomes the steady state error (or DC offset), and limits the switching frequency range, which are the two common problems associated with sliding-mode controllers. The IC is designed and fabricated on a 0.35um CMOS process occupying an active area of 2.72mm-squared. Measured peak efficiency is 83%.
Book Synopsis Sliding Mode Controllers for Power Electronic Converters by : Axaykumar Mehta
Download or read book Sliding Mode Controllers for Power Electronic Converters written by Axaykumar Mehta and published by Springer. This book was released on 2018-12-13 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book proposes a proportional integral type sliding function, which does not facilitate the finite reaching and hence the responses of the load voltage results in an exponential steady state. To facilitate finite time reaching, it also presents the new Integral Sliding Mode Control with Finite Time Reaching (ISMCFTR). The book also extends the application of the proposed controller to another type of PEC, the DC-DC Boost converter, and also proposes the PI type sliding surface for the Zeta converter, which is non-inverting type Buck Boost converter. An important source of practical implementations, it presents practical implementations as simulation and experimental results to demonstrate the efficacy of the converter.

Download or read book Digital Linear and Non-Linear Controllers for Buck Converters written by Shyama M. and published by LAP Lambert Academic Publishing. This book was released on 2012-05 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Issues in the design and implementation of digital controllers for a DC-DC converter using linear and nonlinear control methods were investigated in this dissertation. The small signal models of the buck converter, obtained using standard state space averaging techniques, were utilized.PID controllers were designed for generic buck converter using standard frequency response techniques.The small signal models of the converters change with the variations of the operating point. Since the linear controllers were designed based on the small signal models, they were not able to respond effectively to changes in operating point. To achieve a stable and fast response, nonlinear control methods were applied to the buck converter. Since fuzzy controllers don t require a precise mathematical model, they are well suited to nonlinear, time-variant systems. Fuzzy controllers were designed for the buck converter. Fuzzy systems can handle non-linear characteristics. They can be designed to adapt to varying operating points. By using fuzzy controllers we can reduce both overshoot percentage and settling time. It is implemented using TMS320C6713

This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mobile applications necessitate nowadays huge digital-resources. Power management of a digital System-On-Chip (SOC) is based on dynamic voltage scaling. DC/DC converters used to supply the digital SoCs are facing stringent constraints with respect to load-transients, line-transients and reference tracking. Hysteretic control is known as the most convenient control scheme with a fair trade-off between transient performances, analog implementation and power consumption, particularly for one-phase architecture. The thesis focuses on-board DC/DC with a significant constraint on footprint (i.e. on components count and values). Fixed switching-frequency hysteretic control has been experimented with significant results. Transient performances are reduced due to latency introduced in the switching frequency control. The present study focuses on the improvement of the concept as well as its implementation and the analysis of stability. A new analog implementation of the sliding-mode control is presented with switching-frequency control using a particular analog phase-locked-loop but preserve transient performances. The DC/DC converter is implemented in CMOS 130nm by STMicroelectronics. The switching frequency range has been voluntarily limited and excludes the possible integration of passive components for the sake of silicon access. A hybrid demonstrator is presented with efficiency higher than 80 % between 2.4 mW and 960 mW output power.

This book was released on 2005-10-17 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sliding mode control is a simple and yet robust control technique, where the system states are made to confine to a selected subset. With the increasing use of computers and discrete-time samplers in controller implementation in the recent past, discrete-time systems and computer based control have become important topics. This monograph presents an output feedback sliding mode control philosophy which can be applied to almost all controllable and observable systems, while at the same time being simple enough as not to tax the computer too much. It is shown that the solution can be found in the synergy of the multirate output sampling concept and the concept of discrete-time sliding mode control.
