If the increasing degree is more than default second electric current increasing degree, default second proportionality coefficient is reduced into default the
Four correction values, then execution step S305.
When default 3rd correction value noted earlier and default four correction value is chosen, need to consider essence
Degree control requires and real system parameter that the more little then system accuracy of choosing is higher, but can accordingly increase and be
The amount of calculation of system, causes system unstable.Also, default 4th correction value is more than default 3rd correction value.
S305：Judge biphase current and whether less than default 4th current differential.
After the amendment of step 303 or step S304 has been carried out, working as during determining whether overlapping commutation
Front conducting mutually and next phase two-phase-region casting electric current and whether less than default 4th current differential, this presets the
The 10% of average running current of the preferred switched reluctance machines of four current differentials under current load situation.
Terminate this amendment if biphase current and if being less than default 4th current differential, if be also greater than
Default second current differential then goes to step S302.
Default first current differential be can be seen that with default 3rd current differential from practical operation step above
Identical, it is identical with default 4th current differential to preset the second current differential, default first electric current increasing degree with it is pre-
If the second electric current increasing degree is identical.
