Problems solved by technology

In the traditional design, the controller of the servo control system only adopts one control strategy, which leads to its narrow application range and can only drive the load in a certain fixed mode. When the driven load object changes can not meet the control requirements
Second: When driving the load, if a fault occurs or the driving load changes greatly, the collected signal will also change gre

Embodiment Construction

[0018] The intelligent reconfigurable flexible drive controller is further described below.

[0019] Such as figure 2 or Figure 4 As shown, the controller includes a microprocessor chip DSP28XX, the latest programmable logic device CPLD, intelligent power module IPM, servo motor, TCP / IP network module, RS485 serial communication module; the use of digital signal processing chip DSP28XX and programmable logic device CPLD Combined with the construction of a combined architecture of related circuit modules such as driver operation control, signal acquisition and data communication, the signal fault detection of the driver system is completed, and the command input and feedback signal, position loop, and speed loop PID calculation are processed. The output current Iu and Iv of DSP are used as the current given signal of the analog current loop after D / A conversion, and the third phase current Iw =- (Iu + Iv). The three-phase current given signal is compared with the actual cur...

Abstract

The invention discloses an intelligent reconstruction flexible motor driven controller which comprises a digital signal processing module, a CPLD module, an intelligent power module, a sensor module and a host computer. The invention is characterized in that: output current of the digital signal processing module outputs a PWM wave through the CPLD module; output of the CPLD module is connected with the intelligent power module through base electrode driving; the sensor module acquires feedback current, load torque and moment of inertia of a target motor and outputs the feedback current, the load torque and the moment of inertia to the digital signal processing module; the digital signal processing module is connected with the host computer through a communication line; the host computer receives the feedback current, the load torque and the moment of inertia of the digital signal processing module, employs a flexible control method, and sends a corresponding control strategy to the digital signal processing module. According to a driver, the corresponding control strategy is adjusted according to the change of load, and control precision and system stability are raised.

Description

technical field [0001] The invention belongs to the field of drive controllers, and in particular relates to an intelligent reconfigurable flexible motor drive controller, which can select a corresponding control strategy to control a servo motor according to different moments of inertia. Background technique [0002] With the wide application of high-performance microprocessors in motor speed control systems, full digital control methods have been widely used in various control systems. It not only makes the system have diversified functions, high precision, high reliability, and intelligence. It also provides a platform for the application of new control theories and methods. It is especially worth mentioning that the latest servo control system has begun to use a new type of module that integrates control circuit functions and high-power electronic switching devices, called Intelligent Control Modules (Intelligent PowerModules, referred to as IPM). This device integra...
