Embodiment Construction

[0013] The present invention will be described in further detail below. See Figure 2.

[0014] The controller mainly includes: DSP processing unit 19, CPLD chip 18, FLASH memory 17, AD converter 14, DA converter 15, FIFO memory 16, CAN bus communication module 25 in hardware.

[0015] The DSP processing unit 19 is oscillated by an external crystal, and the PLL circuit inside the DSP processing unit 19 is frequency multiplied to generate a clock signal. By setting the working mode of the DSP processing unit 19 to the microcomputer mode, the boot loading function of the program can be realized when the chip is reset. In order to improve the reliability of the DSP processing unit 19 during operation, a processor monitoring circuit 25 is configured, which can monitor the chip voltage of the DSP processing unit 19, and also has a watchdog function. Once the core voltage is lower than the normal value, or receiving If the dog feeding signal is not output by the DSP processing unit 19, a...

Description

Technical field [0001] The invention belongs to electromechanical servo control technology and relates to an embedded intelligent controller based on DSP. Background technique [0002] The electro-hydraulic load simulator is a typical position disturbance electro-hydraulic force (moment) servo system. One of its main applications is to load the rudder system of missiles and aircrafts to simulate the aerodynamic load on the rudder surface during flight. The loading torque required for this type of system is not very large, but it affects the bandwidth of the loading system. The high precision requirements are a difficult point in the development of a force (moment) servo system. [0003] The performance indicators of missiles and aircraft are closely related to their flight control systems. In the development process of missiles and their flight control systems, relevant information was often obtained through destructive experiments such as shooting targets. Not only was the cost ...
