Some of the assumptions made during the guidance algorithm design for an impulsive orbit transfer becomes invalid in case of a low acceleration system where the orbit transfer is achieved by means of a long duration burn. The long duration burn results in considerable loss of energy due to gravity/arc losses. Also in case of an elliptical to circular orbit transfer, the algorithm is very sensitive to its ignition point and a wrong ignition point manifests as severe eccentricity in the achieved orbit and excessive fuel consumption as well. This paper proposes a simple yet effective velocity based Gravity Compensated Long Duration (GCLD) Orbit Transfer guidance algorithm that accounts for the gravity/arc losses during the thrusting phase. The proposed algorithm caters for in-plane and out-of-plane requirements and thereby meets the targeted orbital conditions with minimal deviations. The paper addresses the difficulty of encountering inclination correction at points near the anti-node and it also proposes a kinematic condition based adaptive ignition logic which ensures that the targeted orbital conditions are achieved with reduced fuel consumption.","PeriodicalId":382373,"journal":{"name":"2021 Seventh Indian Control Conference (ICC)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121865214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They can perform unique actions such as grasping delicate objects, robotic surgeries, etc. The mathematical modeling technique of soft robots is still in the development stage. In this paper mathematical model of a soft pneumatic, gripper has been proposed with finite element method and system identification technique. A soft pneumatic gripper or an actuator works on the principle of applied pressure which have limbs used to grasp objects of different shapes and size. The bending of these limbs has to be controlled to obtain perfect grasping. Classical sliding mode controller (SMC) is one of the popular control techniques that has been used the control the bending deformation of soft pneumatic grippers, but it suffers from the chattering problem. The higher-order sliding mode controller (HOSMC) technique has not been yet applied to control the bending deformation of the gripper. In this paper, HOSMC has been proposed to control the bending angle of the soft gripper which eliminates the unwanted chattering. The simulation results prove the efficacy of the controller.","PeriodicalId":382373,"journal":{"name":"2021 Seventh Indian Control Conference (ICC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125514077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed control strategy is designed by employing the extended state observer (ESO) with integral sliding mode control (ISMC). The proposed scheme attenuates all the uncertainties without using the upper bound knowledge of uncertainties. The application of ESO compensates for the effect of uncertainties and disturbances, which helps in significantly reducing the input chattering from ISMC because the discontinuous control of ISMC is not primarily employed for disturbance rejection. The ISMC is exploited to improve the system convergence rate and ensure robustness from the starting time $t=0$ by eliminating the reaching phase. The theoretical analysis of the closed-loop system guarantees the asymptotic convergence of system states. Besides, the performance of the proposed methodology is validated through numerical simulation. Moreover, the efficacy of the proposed controller is also illustrated by comparing its simulation results with a state-of-the-art method.","PeriodicalId":382373,"journal":{"name":"2021 Seventh Indian Control Conference (ICC)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125637165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed control strategy does not require prior information about the maximum power point as well as is also successful to eliminate any offset present in the output power, increases the speed of convergence and damps the transient oscillations.
