摘要： To maximize the production run speed of a sheet fabrication machine such as a turret punch press, and yet at the same time maintaining the requisite accuracy for each part produced from the production run, historical data pertaining to the various parameters for effecting the positioning moves of a worksheet are measured and collected using a reference machine or a prototype machine. For each positioning move to be effected, the CNC controller of the system retrieves the historical data from a database and, using that historical data, calculates the various parameters that affect the positioning move. By using fuzzy logic, the controller becomes, in a sense, self teaching, especially if updated historical data are provided to its database store to enhance the accuracy for later positioning moves. In addition to measuring and collecting historical data from reference or prototype machines, static process control (SPC) tests may be performed for different types of worksheets under different loads. The data collected from the SPC tests are stored and can be used as the historical data. Using historical data to calculate the next positioning move, i.e., by using the past to forecast or predict the future, the maximum allowable speed is obtained for each positioning move. At the same time moves that will produce parts that have dimensions that are within the predetermined required accuracy threshold are ensured.

摘要： A control system includes a controller. The controller repeatedly excites a control loop characterized by parameters having randomly selected values for each excitation and scores a response of the control loop to each excitation relative to a target signal until the scores no longer achieve a value less than a minimum of the scores for a predefined number of excitations occurring after the excitation yielding the minimum of the scores to auto-tune the control system.

摘要： A flexible closed-loop controller capable of being quickly and easily configured for a broad range of applications. The controller contains a set of control elements that may be configured or reconfigured for any specific application. Built-in configuration management automates configuration of the control elements dependent on user commands or operating conditions. The controller is autonomous after initial configuration, although it may be used interactively. This flexible closed-loop controller is suitable for switching power supplies, linear amplifiers, AC inverters, battery chargers, electronic loads, temperature and pressure management, motor or actuator drives, as well as industrial automation, data acquisition, and automatic test equipment. The controller reduces development time and cost, reduces parts count and cost, and improves performance and reliability of real-time closed-loop systems.

摘要： An earth moving or construction equipment implement control system is disclosed. The control system includes a fuzzy logic controller that is connected to an electro-hydraulic valve. An implement position sensing system senses the height of the implement. A set point is compared to the implement position to produce an implement position error signal which is an input to the fuzzy logic controller.
