Using the traditional method to control the transmission process of the tension tower hydraulic tightening device, there is a problem of slow speed step response in the range of device operating speed from 12km/h to 32km/h. For this reason, this paper designs a programmable logic controller-based transmission control method for the hydraulic tightening device of the tension tower. The two-phase static coordinate system is introduced to obtain the voltage equation, flux equation, electromagnetic torque equation and electromechanical motion equation of the hydraulic drive system, and then the mathematical model of the hydraulic drive system is constructed. The full-order observer is regarded as an adjustable model, the appropriate Lyapunov function is selected, and the function stability of the full-order observer is derived, so as to realize the identification of the speed of the tension tower hydraulic tightening device. Based on this, a transmission control model is constructed based on programmable logic controller to realize the transmission control of the tension tower hydraulic tightening device. Experimental results prove that the speed step response rate of this method is higher than that of the traditional method, and the response performance is improved.
