  • This paper presents a speed control strategy using a Takagi-Sugeno (T-S) fuzzy model for interior permanent magnet synchronous motor (IPMSM).We derive the sufficient conditions for the existence of the regulator in terms of linear matrix inequalities (LMIs), and also give LMI parameterizations of the gain matrices. Finally, the validity of the proposed fuzzy speed controller is confirmed through simulation study on a prototype IPMSM drive system.

  • A laboratory test-rig for groundnut planter was developed for testing and calibrating the pneumatic seed metering mechanism. The experimental test rig mainly consists of main frame, seed hopper, seed metering system, power transmission system and sticky belt system. The metering unit is incorporated with a vertical seed plate held in a vacuum retaining chamber to singulate the seeds. A dial type vacuum gauge was provided in order to record the variation in suction pressure. A sticky belt was used to simulate the field surface during laboratory investigation.

  • Weed management is a tedious task, especially in organic crop production, as synthetic herbicides are prohibited and manual weeding is relatively expensive or unavailable. However, mechanical weed control is one of the options that can be implemented by growers to control weeds but the main challenge to both practical farmers and researchers is the selective control of the intra-row weeds. Based on this challenge the objective of the study was to evaluate the minimum plant to plant distance required to operate the developed automated intra row weeder with minimum plant damage.
