Embodiment Construction

[0015] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0016] The present invention realizes a vibration suppression circuit for steering gear; in the rudder system controlled by an analog circuit and using a harmonic reducer as a deceleration mechanism, due to the low stiffness of some types of harmonic reducer, when the steering gear and the rudder surface are assembled Finally, under the conditions of high frequency response and large inertia, the disturbance torque formed by the air rudder surface during the movement can easily cause the rudder surface to vibrate. The steering gear needs to have a large angular acceleration in the process of accele...

Abstract

The invention provides a rudder jitter suppression circuit and a rudder system. The rudder system includes a feedback circuit as well as an adder, a signal amplifying and conditioning circuit, a jitter suppression circuit, a signal processing and power amplifying circuit and a servo rudder which are connected with one another sequentially; the input end of the feedback circuit is connected with the output end of the servo rudder; the first input end of the adder is used for receiving external rudder control signals; the second input end of the adder is connected with the output end of the feedback circuit; and the jitter suppression circuit includes an amplifier, a first one-way conduction element, a second one-way conduction element, a capacitor, a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor and a sixth resistor. With the rudder jitter suppression circuit and the rudder system of the invention adopted, interference signals can be effectively filtered out, and at the same time, self-excited oscillation of a resistance-capacitance circuit at the input end of the circuit can be greatly suppressed, which can well suppress the jitter of a rudder in a large-inertia rudder system having high bandwidth requirements, and therefore, the stability of the system can be ensured.

Description

technical field [0001] The invention belongs to the field of steering gear control, and more specifically relates to a steering gear shaking suppression circuit and a steering gear system. Background technique [0002] In recent years, with the continuous improvement of the strike accuracy and maneuverability requirements of the flying attack weapon system, the accuracy and stability requirements of the matching rudder servo system are getting higher and higher. The performance requirements of the current rudder system are developing in the direction of large inertia and high frequency band. [0003] At present, many rudder servo systems still use analog circuit control, harmonic reducer and DC motor control. The control method is relatively simple and the control theory is relatively mature. However, under the conditions of high frequency band and large inertia, the performance of the steering gear often has some difficulties in meeting the requirements of the overall syst...
