According to the work characteristics of the electromechanical actuator, a control scheme of direct DC electromechanical actuator based on discrete-time variable structure controller is designed. The effect of hinge moment is considered in the mathematical model, and the coefficients of its transfer function are appropriately amended. The effect of the three parameters in the design of discrete-time...
This paper presents a Sin microstepping method which can achieve constant torque, accurate position control and eliminate low frequency oscillation. The driver adopts FPGA as core, achieving 256 subdividing and PID control algorithm. This paper uses EDA Simulator Link as a co-simulation tool, which provides an interface between Modelsim and Simulink accelerating the function verification. The co-simulation...
