The invention entirely uses analog type circuits to realize, which has high real time property, strong anti-jamming capability and high and reliability, etc.; four-closed-loop moment motor drive control module is provided with favorable control performance and control quality; when the current flows through the motor coil, the invention implement two stage overcurrent protection policy, which allows the motor current protection to be safer, and the motor to run more dependable.

Description

(1) Technical field [0001] The invention relates to a position drive module of a DC torque motor with a limited angle of rotation, in particular to a position drive module of a DC torque motor with a limited angle of rotation with an output capacity exceeding 15 N.m force, belonging to the field of automatic control systems. (2) Background technology [0002] Adopting electronic speed regulation technology is the main way to improve the speed regulation performance index of diesel engine (or natural gas engine, dual fuel engine, etc.), and the actuator is the key component in the electronic speed regulation system of diesel engine. It converts the electrical energy of the system into mechanical energy, and drives the control object of the system, so as to achieve the purpose of control. Therefore, the performance and characteristics of the actuator directly affect the performance of the entire diesel engine electronic speed control system. In order to meet the dynamic and s...

AI Technical Summary

Problems solved by technology

Regardless of whether it is digital or analog, the control law of the system described in the above literature is simple, and the dynamic characteristics and anti-interference ability are poor.

Single closed-loop motor control with single position loop or current loop or double closed-loop motor control with position loop and current loop cannot meet the speed control requirements of diesel engines

For diesel engines, it is difficult to guarantee the real-time performance of complex control laws realized by digital control
