Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing:

[0015] Such as figure 1 As shown, this fast torque tracking control strategy is completed through the control circuit. The control circuit includes a PI regulator, a sawtooth wave generator, a clock circuit, a comparator, an RS flip-flop, an adder, and two input terminals of the adder. One input terminal receives the servo position signal converted by the conversion circuit, and the other input terminal receives the signal from the current sampling circuit. After the output terminal of the adder passes through the sampling resistor, it is connected to the same input terminal of the comparator as a comparison The same direction input signal of the torque sensor; the output signal of the torque sensor is compared with the torque given signal, the output end of the subtractor is connected to the PI regulator, and the output end of the PI regulator is connected to the input end...

Abstract

The present invention relates to a fast torque tracking control strategy. This fast torque tracking control strategy is completed by a control circuit, and the control circuit includes a PI regulator, a sawtooth wave generator, a clock circuit, a comparator, an RS flip-flop, and an adder. , the two input terminals of the adder, one input terminal receives the servo position signal converted from the conversion circuit, the other input terminal receives the signal from the current sampling circuit, the output terminal of the adder passes through the sampling resistor, and the comparator Connected to the same input terminal of the comparator as the same input signal of the comparator; the output signal of the torque sensor is compared with the torque given signal, the output terminal of the subtractor is connected to the PI regulator, and the output terminal of the PI regulator is connected to the The input end of the second subtractor is connected to the multiplier on the other hand, the output end of the multiplier is connected with the sawtooth wave generator, the output end of the sawtooth wave generator is connected to the other input end of the second subtractor, and the output end of the subtractor is compared with connected to the inverting output of the device. The invention realizes that the electric load simulator can track the change of the given torque in real time, quickly and accurately.

Description

[0001] Technical field: [0002] The invention relates to a circuit for controlling an electric load simulator to apply a payload spectrum to a steering gear, in particular to a fast torque tracking control strategy. [0003] Background technique: [0004] At present, the torque tracking control strategy of the PWM converter of the loaded motor generally adopts the traditional linear feedback control strategy, that is, the torque current feedback single closed-loop control and the torque, speed and current three-loop control, and the regulator generally adopts PID regulation. Since the loaded motor PWM converter is essentially a strongly nonlinear dynamic control system, it is difficult to achieve satisfactory results in the dynamic response, anti-disturbance performance and steady-state error of the loaded motor PWM converter based on linear feedback control during torque loading. Control effect. [0005] Invention content: [0006] The purpose of the present invention is to...
