摘要： An angle-calculation apparatus for three-phase optical encoder receives three-phase sinusoidal signals 120 degree phase from the optical encoder and obtains angle information for a motor rotor. The angle-calculation apparatus includes an A/D converter, a digital signal processor (DSP), a phase digitalizer and a digital counter. The A/D converter converts three-phase analog signals of the optical encoder into three-phase digital signals. The phase digitalizer converts the three-phase analog signals into digital phase signals. The digital counter generates a counting value based on the digital phase signals. The DSP performs an inverse trigonometric function calculation on a relatively linear region of the three-phase digital signals to obtain the angle information. The DSP obtains the rotation turn number and rotation direction of the motor rotor according to the counting value.

摘要： A high-precision absolute type encoder apparatus includes a controller electrically connected to an incremental type encoder and generating a control signal to the incremental type encoder, a comparator electrically connected to outputs of the incremental type encoder and generating first pulse signals, a latch unit electrically connected to outputs of the comparator and generating second pulse signals by latching the generating first pulse signals. When power failure occurs, the controller generates the control signal as successive pulses with predetermined period to drive the latch unit and the incremental type encoder. Therefore, the controller knows angular information of the incremental type encoder by counting the second pulse signals. The absolute angular information can be obtained by combining the angular information and an initial position after power failure.

摘要： A multiple-point smoothing method for motor-speed estimation. The output of an encoder is over-sampled to obtain over-sampled position differences according to an over-sampling factor M. The over-sampled position differences are averaged to obtain an initial speed estimation. The initial speed estimation is low-pass filtered to obtain a final speed estimation. The final speed estimation is sent to a speed controller to control the speed of a motor. Alternatively, in a composite multiple-point smoothing scheme, the initial speed estimations based on two over-sampling factors are obtained. One of the initial speed estimations is selected based on an average of the two estimations, and the selected initial speed estimation is further processed to obtain a final speed estimation. The method of the present invention can reduce ripple in estimated speed of motor when the motor is operated at high speed.

摘要： A method of instant estimation of the rotor inertia of a load motor is disclosed. The adaptive filter accompanied with the Least Mean Square Rule is introduced to instantly estimate the rotor inertia of a load motor. One input of the adaptive filter is the current signal of a model motor whose rotor inertia is known, and the other is the deviation current signal between the model motor and the drive motor. Once the two inputs are determined, the rotor inertia of the load motor will then be calculated using the Least Mean Square Rule and the adaptive filter.
