Torque

The purpose of the field-oriented control (FOC) is therefore to create a tool that allows the decoupling control of the flux and torque-producing current components from the three-phase AC currents flowing in the coil. The FOC drive system is a system based on the principle of decoupling the above power components thanks to the stator current feedback control (the innermost circuit of the drive system). The FOC-type control method belongs to the class of vector control methods for electrical machines.

The thesis aims to propose some control techniques for mobile target Robot-camera. After that, I studied some of the torque control techniques of joints for the Robot-camera system sticking to the mobile target and the Robot-camera system, paying attention to the motivating motor sticking to the mobile target. Finally, the author also proposed some control algorithms for Robotic-camera arm system with irregular model, external noise and preventing system degradation, using nonlinear sliding controller (TSMC) in combination with Artificial neural networks to estimate uncertain numbers.

The robot equations of motion are obtained from the implemented program and verified against those obtained using only Lagrange equation. The output of program for the 3 DOF robot was used to find the optimal torque using analytical optimization analysis for a given set of parameters. This procedure analysis can be used as a benchmark analysis for any optimization technique.

Nghiên cứu này đã được tiến hành tại một trại heo nuôi công nghiệp trong thời gian từ tháng 1/2015 đến tháng 3/2016. Kỹ thuật PCR đã được áp dụng để xác định sự hiện diện của virus Torque teno sus (TTSuV1, TTSuV2) và PCV2 trong các mẫu mô và mẫu huyết thanh của heo ở trại này. Kết quả nghiên cứu cho thấy heo ở trại khảo sát có xu hướng nhiễm TTSuV1 và TTSuV2 trong máu tăng dần theo lứa tuổi.

A comparison between three methods applied to parallel robot control namely: Computed torque controller, sliding mode control and sliding mode control using neural networks is presented in this paper. The simulation results show that PD control method is only accurate when model parameters are precisely identified.

The presence of dicumyl peroxide (DCP) causes the changes in relative melt viscovity and the morphology of blend LLDPE/EVA. It raises torque momen amplitude of polymer blend at the balance state of melting of the polymers mixture. The results of TGA show that the durability against thermo-oxidation of polymer blend containing DCP is higher than that of without DCP. The SEM photographs also shows that DCP makes LLDPE and EVA phases dispersing into each other better than the original polymer blend.

A drive sizing makes sure that the drive has enough torque to satisfy the load requirements to overcome friction losses, provide sufficient load thrust, and provide enough acceleration torque for the type of acceleration required. Once the drive-sizing requirement is satisfied, the servo drive stability must be addressed. Stabilizing the servo drive is a matter of adjusting the servo compensation. All industrial servo drives require some form of compensation often referred to as proportional, integral, and differential (PID).

INTRODUCTION In the application of industrial servo drives to machines it is important that the drive be large enough to meet all the load torque requirements and be stable. It is necessary to make sure that the servo drive torque rating is large enough to meet the load thrust and acceleration requirements plus the machine friction losses; an organized method to accomplish this is referred to as ‘‘sizing the drive.’’ There are many drive-sizing software programs available from commercial servo drive suppliers.

AC motors convert AC electrical energy to Mechanical energy. AC motors: the armature of rotor is a magnet (different to DC motors). the stator is formed by electromagnets (like in DC motors). Effects of AC Supply on Magnetic Poles Consider the rotor to be a permanent magnet. Current flowing through conductors energize the magnets and develop N and S poles. The strength of electromagnets depends on current. First half cycle current flows in one direction. Second half cycle it flows in opposite direction...
