Abstract

In a motor current optimization control method and system, while the motor runs steadily at a set speed, one d-axis current command value of the input current is set to 0. Then, the d-axis current command value is step-wisely increased by an increment at least twice. At least three real-time feedback current values can be collected from detecting a feedback current of an AC power. When an instant detected is smaller than the previous detected, the d-axis current command value is increased. When the instant detected is greater than the previous detected, the d-axis current command value corresponding to the previous detected is a minimum feedback current value and is defined as the optimized d-axis current command value. The optimized d-axis current command value is set as the d-axis current command value of the input current to control the motor to keep running steadily at the set speed.

A detection temperature is periodically detected and updated with a detection period, the detection temperature in the previous detection period is a previous temperature, and the detection temperature in the instant detection period is a current temperature. A control module performs RPS-m for a compressor when the current temperature falls within the adjustment interval, RPS+0 when the current temperature falls within the allowable temperature interval, and RPS+o when the current and previous temperatures fall within the convergent cooling interval and the allowable temperature interval, respectively. Detection, judgment and control are repeated until the current temperature falls within the allowable temperature interval.

Abstract

A method and a device are used to generate a control command. A resolution base value and a resolution-tick corresponding function are created. A first operation frequency value, a minimal tick value and a resolution value are received to calculate a resolution ratio and a second operation frequency. A conversional tick value is calculated. If or not the conversional tick value is greater than or equal to the minimal tick value is determined. If the conversion tick value is smaller than the minimal tick value, the minimal tick value, the conversional tick value and the second operation frequency are used to calculate a conversional operation frequency. A conversional resolution ratio is calculated according to the first operation frequency and the conversional operation frequency, and also a modified tick value is calculated. The control command is output according to the modified tick value, the first operation frequency and the conversion operation frequency.

Abstract

A control command resolution adjustment method and a command generation device are disclosed in present invention. The control command resolution adjustment method is used to adjust a control command form the command generation device. A calculation frequency value via the command generation device is analyzed. The control command is received and a transform frequency value via the control command is analyzed. A first resolution value is calculated from the calculation frequency value and the transform frequency value. The first resolution value is distinguished greater than or equal to a minimum resolution value. When the first resolution value less than the minimum resolution value, an added calculation frequency value is calculated from the calculation frequency value and a frequency added value. A second resolution value is calculated from the added calculation frequency value and the transform frequency value. When the second resolution value greater than or equal to the minimum resolution value, the control command via the second resolution value is outputted.

Abstract

Disclosed is a novel manufacturing method, which is a manufacturing procedure wherein a capsule is formed by combining starch, λ-carrageenan, metallic salt, a plasticiser, and water as the structural component composition for the raw materials for the outer-skin part of the capsule, and which has enhanced the drying ability of conventional rotary-die type soft capsule manufacturing methods, enabling the water content of a capsule outer-skin sheet to be freely adjusted, and which also has improved the previously problematic post-formation hardness-stability of the capsule. In the disclosed soft capsule manufacturing method a capsule is formed by combining starch, λ-carrageenan, metallic salt, a plasticiser, and water as the structural component composition for the raw materials for the outer-skin part of the capsule. In addition to being a novel method wherein trisodium citrate is mixed as the metallic salt, the method is characterised by the introduction to conventional rotary-die type automatic soft capsule manufacturing methods of a drying procedure for the capsule outer-skin sheet using medium wavelength infra-red radiation, thus enhancing drying ability and enabling the water content of the capsule outer-skin sheet to be freely adjusted.
