Abstract: A control system for a synchronous electric motor controls the synchronous motor so that the phase of a current determined based on a magnetic pole position of a moving element of the motor may shift to a phase where maximum torque may be obtained. A magnetic pole position correcting section determines a magnetic pole position correction to be added to a relative magnetic pole position. In connection with a polarity change determining section which determines whether or not a polarity of an acceleration difference changes, a basic correction adjusting section switches computation between an incremental operation of incrementing a basic correction and a decremental operation of decrementing the basic correction by a correction increment/decrement. When the correction increment/decrement becomes a predetermined lower limit value B or less, the basic correction adjusting section stops the computation. The basic correction at that point is determined as a finally-determined magnetic pole position correction.

Abstract: A method of estimating load inertia for a motor is provided that can estimate the load inertia even when a cogging torque of the motor is large or resonance occurs in the mechanical system of the load. Vibration is detected in an acceleration feedback signal. An estimated inertia gain Kn is multiplied by a coefficient ? of zero (0) or more but less than one (1) when the detected vibration is equal to or more than a predetermined level, or the estimated inertia gain Kn is multiplied by a coefficient ? of one (1) when the detected vibration is less than the predetermined level.

Abstract: A speed controller includes a speed integration compensation low-pass filter, an integral control system, a proportional control system, and a multiplication device means. The speed integration compensation low-pass filter has a transfer function corresponding to a delay of a speed control system. The integral control system 136 is multiplied by an integral gain by a multiplier and integrated by a speed integrator before being supplied to an adder. The adder adds an output of the proportional control system and an output of the integral control system and outputs the result to the multiplier, which in turn multiplies the output of the adder by a proportional gain and outputs the result as a torque command. The multiplication means multiplies the output of the integral control system and the output of the proportion control system by a speed proportional gain and outputting the value of the torque command.

Abstract: A transaction processing method is provided for a transaction management system which processes transactions using settlement cards. In the transaction processing method, a transaction process is executed based on individual control information that is input at each transaction and transaction information for the transaction. A judgment is made based on the transaction information whether or not the transaction satisfies at least one count-up condition indicating a predetermined range of transaction types. When the transaction meets the count-up condition, numerical information indicative of the number of transactions satisfying the count-up conditions is added. A determination is made whether or not a numerical value represented by the numerical information after the addition is within a range specified by extraction conditions.

Abstract: An electronic settlement system processes settlements that are conducted using credit cards through a communication line connecting a server of a credit card company to card-processing devices of member stores or terminals of customers. The electronic settlement system includes a device that provides personal information of customers to member stores based on the agreement by the customers to provide such personal information, and a device that provide the customers with preferred services either from the credit card company or the member stores in exchange for the personal information provided. Furthermore, the electronic settlement system may includes a device at the card company to receive fees for providing the member stores with the personal information of the customers. The electronic settlement system enables the customers to receive services, the member stores to utilize accurate personal information, and the card company to receive fees from the member stores.
