    摘要: A system for detecting a voltage and/or current of a single phase and/or polyphase alternating current includes a sample-hold circuit that detects and holds instantaneous values of a plurality of sampling points over a fixed time period of the alternating current as sampled values. A first calculation circuit calculates the real part and the imaginary part of the Fourier coefficient with respect to a fundamental wave and/or a component of the positive-phase sequence of the alternating current detected from the plurality of sampled values thus held and outputs respective calculated values thereof. A second calculation circuit performs a predetermined calculation to the calculated values of the real and imaginary parts and thereby calculates and outputs the amplitude of the fundamental wave and/or component of positive-phase sequence of the alternating current.

    摘要: An industrial expert system for use in designing a plant system or device thereof and in fault detection, includes a knowledge base having a rules-section for describing deductive inference rules. Also included is an expression-section for describing a calculation formula of equality with either a right side or left side being a simple term having a value and the other side being polynomial including known functions. Also included is an attributes-section for declaring the nature and value of each of the attributes cited in calculation and inference and for declaring parameters for controlling communication between a process of deductive inference and a calculation process according to calculation formulas. A deductive inference engine performs deductive inferencing on the basis of the rules, calculation formulae and the attributes stored in the knowledge base. This system uses a simple construction to efficiently perform detection of fault logic by using specific formula or calculation of parameters representing features of a fault which are to be performed during an inference.

    摘要: A commutation compensation device for a DC machine of the type in which in addition to an interpole coil for the armature current flow, an interpole is provided with an auxiliary interpole coil and in response to a reference exciting current calculated based on the rate-of-change of the armature current, the exciting current for accomplishing the commutation compensation is caused to flow through a controlled DC power source to the auxiliary interpole coil. In order to further improve a degree of commutation compensation, when the commutation is degraded, the armature current adversely affecting the commutation, the rate-of-change of the armature current and so on are automatically calculated and evaluated by commutation degradation rate calculator, whereby a commutation compensating rate is automatically obtained and in response to the commutation compensating rate the corrected exciting current is delivered to the auxiliary interpole coil.
