Super-twisting Algorithm Based Sliding Mode Controlled Boost Converter
Abstract: This work provides analysis of boost converter with super-twisting algorithm under sliding mode operating in continuous conduction mode. The super-twisting algorithm reduces the chattering effect which is inherent in conventional sliding mode control. Generally, chattering increases heat losses, thereby decreasing the performance of the boost converter. The aforementioned control strategy minimizes the initial current peak and provides highly improved output voltage regulation irrespective of the input voltage perturbation and load …

Research to Improve the Performance of Position Control System Using the SPMSM Based on the Time-varying High Order Sliding Mode Control Method
Abstract: This paper proposes the method of position control system design using permanent magnet synchronous motor (PMSM) based on the time-varying high order sliding mode control (TVHOSMC) strategy. In the conventional sliding mode control (SMC) system the chattering phenomenon appears in the vicinity of the sliding plane and while the error state of system reaches the sliding plane, the system is sensitive to the external disturbance and the parameter change. Thus, …

Correlation of Ki-67 Score with Nottingham Histological Grading in Carcinoma Breast: A Single Institution Experience
Abstract: Though it is reasonably well established that Ki-67 positivity is an independent predictor of ultimate prognosis and course of carcinoma breast and its recurrence, many lacunae exist. Ki -67 score correlation with histological grading will establish importance of nuclear antigen Ki-67 as prognostic factor in Indian population. This study was aimed to assess histological grading of breast carcinoma by Nottingham Grading System (Modified Scarff- Bloom- Richardson system) and to correlate …

Sensor Less Control of PMSM using SMC and SMO
Abstract: Some particular PMSM applications do not allow for the proper mounting or use of position sensors. A number of PMSM control problems can be resolved with sensorless PMSM control. It is crucial to have a precise predicted position while avoiding the chattering issue for sensorless PMSM control. This paper establishes a prerequisite for a sliding mode observer (SMO) to enter a sliding surface and offers a sigmoid-based algorithm for position …

Wear Characterization of Al/B4C/CNT Composites for Different Alloying Composition
Abstract: Wear is a surface phenomenon that occurs predominantly at the surface of the material. It is majorly due to the rubbing action between two surfaces that is attributed to solid state contact. As wear is a material removal phenomena occurring at the outer surfaces, it is indeed very apt to develop materials that have wear resistant characteristics. Henceforth in the current work, it is therefore judicially justified to develop a …
