Description

technical field [0001] The invention relates to a CKDY electro-hydraulic execution advanced motor control algorithm. Background technique [0002] The digital control method has links such as sampling, calculation, and duty cycle update, which make the maximum duty cycle of the inverter limited. A commonly used solution in practical applications is to adopt a one-beat lag control method. This method causes a delay in the application of the control quantity, which is prone to overshoot and other phenomena, which is one of the main reasons for the improvement of the dynamic performance of the limited current loop regulator. Many current methods focus on eliminating one-beat lag delay in the feedback channel. The more direct method is to take measures to predict the current value of the next beat in advance, which is equivalent to advancing the input of the regulator by one beat on the feedback channel, which can eliminate the lag delay of one beat on the forward channel. If...
