摘要： A control system for an electronically commutated motor (401) can rotate smoothly to very low speeds without using a high resolution encoder and can respond to variations in load without excessive speed fluctuations. The control system can be applied to motors operating with low resolution encoders and motors operating with sensorless rotor position feedback. The electronic control system can vary the magnitude and frequency of the stator excitation applied to one or more stator phase windings, the electronic control system comprising a frequency setting section (402) and a magnitude setting section (403) characterized by the fact that the frequency setting section (402) is constrained to operate over a limited range of frequencies, the maximum frequency being a function which is closely related to the frequency associated with rotation of the rotor at the desired speed.

摘要： This invention relates to the control of electrical machines and is concerned more particularly, though not exclusively, with the control of flux switching brushless permanent magnet and switched reluctance electrical machines without a mechanical shaft position sensor. Brushless Reluctance and permanent magnet motors can be used in many applications, since they do not require the use of commutators or brushes in supplying electrical power to the rotor of the motor. An electrical machine is provided for converting electrical energy into mechanical energy and/or mechanical energy into electrical energy, the machine comprising a stator and a rotor, the stator having one or more electrical windings wherein at least one electrical parameter of the windings have a cyclic variation related to rotor position; at least one control device for controlling supply of electrical current to or from the or each said electrical winding, and at least one rotor position sensor means for detecting at least one electrical signal related to the cyclic variation of at least one electrical parameter of the or each said electrical winding wherein at least one said rotor position sensor means comprises the steps of measuring the said electrical signal at least once during any part of a switching cycle, conversion of the at least one measured electrical signal to a ratiometric quantity representative of an estimate of the rotor position corresponding to the at least one measured electrical signal and using the said ratiometric quantity in a calculation to maintain the current passing through the or each said electrical winding in synchronism with rotor rotation.

摘要： Open loop methods are commonly used to start a motor, increasing the frequency until the EMF can be detected and a reliable transition to sensorless control can be made. It is the purpose of this invention to disclose an observer, operating during a time when open loop control is being used to drive a synchronous motor, the output of the observer being a signal, E
_I_angle , related to the angle between a rotational EMF vector and the current excitation vector, the observer determining the angle by an iterative calculation incorporating a summation term, the summation term summing the variation of the quadrature component of a rotational EMF vector relative to an estimated EMF position vector, and using the angle output of the observer to update the estimate of the rotational EMF position vector. In a further aspect of the invention the observer output signal,
E_I_angle ,can be used to determine the transition to closed loop control, when the observer output signal reaches a value indicating conditions close to pull out conditions.

摘要： A power supply circuit which offers a high efficiency and cost competitive solution to driving one or more low voltage LED strings from a higher voltage ac or dc supply. The power supply provides a dimming capability either by direct variation of the input supply or independently of the input supply by a simple internal controller. Aspects of the invention may be used without current feedback while obtaining acceptable current regulation, even under significant changes in the LED voltage or number of LEDs in a string. The power supply can drive one or more LED strings from a single power supply without the need to individually monitor the current in each string. A very low cost method to drive three colour LEDs and independently vary the current through each colour of LED to create a low cost colour blending power supply is provided. The power supply comprises at least two conversion stages, a first conversion stage comprising input terminals for connection to an ac or dc supply, an electronic converter with constant output current characteristics and output terminals for connection to at least one second conversion stages. Each second conversion stage comprises input terminals to receive a substantially constant current input from a first conversion stage, current multiplier circuit and output terminals for connection to a load. Circuits according to this invention are particularly suitable for lighting applications, for controlling the large number of LEDs in LED display panels or in backlighting for televisions and LCD displays.
