A parameter carries out operation, and thereby, it is possible to describe the curve graph of arbitrary speed control input-advance angle.
Therefore, it is possible in the case of the special mapping data of no speed control input-advance angle, obtain with it is a variety of
The corresponding advance angle characteristic of motor.
(embodiment 2)
When advance angle controls, advance angle corresponding with speed control input is set, at this point, as shown in figure 3, upper
Within limit value, it then follows an arithmetic expression draws the curve graph of speed control input-advance angle, becomes slope near upper limit value
For maximum curve graph.
In this case, near upper limit value, advance angle occurs larger due to the small variations that speed control inputs
Variation, leads to the decline of the not uniform efficiency of rotating speed.
Therefore, in example 2, inflection point is nearby set in upper limit value, has reached times of upper limit value nearby in advance angle
When meaning value, reduce slope, inhibits the decline of the not uniform efficiency of rotating speed as a result,.
In example 2, advance angle determination section 12 constitutes slope configuration part, corresponding with speed control input setting
When advance angle, as shown in figure 5, the slope configuration part will be until the specified value to upper limit value of the upper limit value less than advance angle
, advance angle be set as more defeated relative to speed control than the advance angle at specified value place relative to the slope that speed control inputs
The slope entered is small.Thereby, it is possible to realize the stabilisation of control.
As the method for the slope for inhibiting advance angle, the change of arithmetic expression, the change of coefficient, the meter to arithmetic expression are considered
Calculate the addition operation of result.For example, in the case of arithmetic expression, at the time of speed control input has been more than defined threshold, tiltedly
Arithmetic expression is switched to expression of first degree by rate configuration part from quadratic expression.
Alternatively, at the time of speed control input has been more than defined threshold, slope configuration part coefficient of variation.Alternatively, in speed
Degree control input has been at the time of be more than defined threshold, slope configuration part by the result of calculation to arithmetic expression carry out additional operation come
Change slope.
Fig. 6 shows to have substituted into the concrete example of the curve graph of speed control input-advance angle of numerical value.At advance angle
When 48 °~58 ° of range, by reducing slope, the decline of the not uniform efficiency of rotating speed can be prevented.
Fig. 7 shows that the arithmetic expression by the range that advance angle is in 48 °~58 ° changes for logarithmic curve graph.Example
Such as, when advance angle is in 48 °~58 ° of range, the operation of the curve graph of input-advance angle is controlled by switch speed
Formula changes slope.In addition, by making initial value when logarithmic switching and advance angle before this be the number at 48 °
Value is consistent, can successfully switch over.
