In this paper, Hybrid Fuzzy-PID controllers for current and speed control loops were suggested. Simulations with MATLAB Simulink for the electric shovel hoisting controllers were implemented and compared with conventional PID controller. Simulation results show that control quality of the hoisting drive is improved with the Hybrid Fuzzy-PID controllers.

The paper presents a new approach to the speed control of a switched reluctance motors (SRM) is that using a back-stepping controller combining with an artificial neuron network based flux estimator. The nonlinear mathematical model of switched reluctance motor (SRM) is established and the back-stepping control strategy is applied to control SRM. The ANN will be used to estimate the flux of the motor instead of approximated model or experimental values.

The paper focuses on the controller designing for the position and speed of non-salient synchronous type axial self-bearing motors. The motor creates the magnetic field to lift the motor along the shaft and generate rotating torque. Firstly, the motor electro-mechanical relations are analyzed to formulate an accurate mathematical model, then a vector control structure is proposed.

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.

The satellite is supposed to move in a circular orbit around the Earth and always require energy for its activities. Therefore, the solar panels need to orient towards the Sun as long as possible to receive the most energy. In the first step, a dynamics model of a satellite disposed by three momentum wheels whose angular speeds controlled by corresponding motors is developed.
