Title: Control equipment of motor
Inventor: KAMIJIYOU HIROTAKA
IPC: H02P27/06
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To avoid quick change of an output at the time of start and at the time of end of the output limit of a motor. SOLUTION: When the condition of output liming is satisfied (S100), output P at this time is calculated (102). When the output P exceeds an output Pmin at the time of output limit, a value obtained by subtracting a specified value ΔP1 from the output P is newly made an output requirement value P. Based on the requirement value P, a torque upper limit value is calculated (S110), and a torque command is controlled to be lower than or equal to the limit value (S114, S116). When the release condition of output limit is satisfied, a value obtained by adding a specified value ΔP2 to the output requirement P is newly made an output requirement value P (S122). Based on the requirement value, a torque upper limit value is calculated (S110).  In each control period, the output is decreased by the specified value ΔP1, or increased by the specified value ΔP2, so that quick change of output can be prevented.
