Item type:Publication, The improved sensitivity of remote robot control via parallel method(2015-12-23); Harnnarong, ShIn a robot control system, the process of data reading affects the consumed time which will directly affect to the time is used in this system. The more channels exist, the more time will be consumed in the robot control system. This work presents the application of parallel reading in the wireless receiver with eight channels for robot semi-automatic control. The software presented in this work was intentionally written as a standard library for Arduino which can read both in sequence and parallel. Obviously the result shows that the all of eight channels, the parallel reading in this work consumed the reading time less than the sequence reading, which decreased the time consumed in the reading process. It affects to improve the sensitivity of remote robot control. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Development of load control and management system(2002-01-01); This paper presents the conservation of electrical energy in building with the technique to develop load control and management system in order to adjust load factor of system. Using the limiting and controlling the maximum demand, we can acquire the prediction and compare it to the maximum demand set point. This system consist computer which works as controller, processor and database unit and works with digital power meter inform of multidrop network by serial communication via RS-485. The control system use PLC to control load via serial communication RS-485. The data of measurement such as voltage, current, power, power factor, energy, etc., can be saved as database and analysis. The load factor adjustment by limiting and controlling maximum demand can reduce the cost of electric consumption and energy generation. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, 4-Quadrant DC motor drive control by BRM technique(2000-01-01); Bunjungjit, S.The 4 - quadrant dc motor drive control, considered the technique of BRM is proposed on the expectation of fast response. Power and torque control are imposed on both no load and loaded condition. The outcome response time is less than 2.5 seconds, when the resolution of input energy supply is 255 waveforms with scan time of 0.667 milliseconds. The ripple is less than 1%.The control condition of 4-quadrant are operated in quadrant I and IV for forward and reverse rotation and quadrant II and III are for sudden braking by regenerative, resulted in giving reversing time less than 3.5 seconds. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, A single-phase PWM inverter controlling base on PLL technique(2011-01-01); Phipek, K.In this paper, the control of the output voltage in a PWM inverter is presented. The single-phase PWM inverter is controlled by using a sinusoidal-pulse width modulation (SPWM) technique, its feedback is controlled with a Phase lock loop (PLL) compensator. The proposed intention is improved output voltage and decreased total harmonic distortion (THD) of the inverter, based on Phase-lock technique and detected phase error of output voltage and reference voltage. Moreover, this method can be applied to greater output of the PWM inverter and better reliability and high-accuracy in order to control methods of PLL. © 2011 SICE. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, A single phase 9-level inverter controlling based on Phase Lock Loop technique(2012-12-01); Phipek, K.In this paper is presented the multilevel inverter which is controlled by Phase Lock Loop (PLL) controller in close-loop system. The multilevel inverter was multiplied voltage levels at output. The inner PLL controller was controlled by PI control in order to firing angle of PWM signal. This control scheme is estimated phase and frequency in DQ-transform of PLL controller on time domain. The PLL controllers were locking constant the frequency and voltage of inverter through the signal estimated in DQ-dimension. The proposed methods determine high-precision and accuracy of switching frequency in PLL characteristic based on time domain. Moreover, in this paper represented the 2<sup>nd</sup> order phase lock loop (PLL) analysis methodology. The 2<sup>nd</sup> order phase lock loop demonstrated in transfer function form that is measured and analysis the signal in time domain. The close-loop control was analyzed the fast response and stability in frequency domain which is obviously behavior of Phase Lock Loop (PLL). © 2012 ICROS. - Some of the metrics are blocked by yourconsent settings
