“…The Fuzzy-PD control is used in the folding machine due to its advantages over conventional controls such as PI or PID. This advantages include; the system is able to reduce oscillation, lessens overshoot, cut settling time, and it is suitable for non-linear processes [20], [21], [22], [23], [24], [21], [25], [26], [27], and [28]. Fuzzy-PD uses input and delta (Δ) errors from the rotary encoder data which has been converted into an angle.…”

The arm manipulator application that has 1 degree of freedom (DOF) can be used to flip folders in folding machines. The used actuator in folding machine is a Brushed DC motor. The Fuzzy-PD control system in this application is using Arduino Mega2560 microcontroller. Application of Fuzzy-PD control system on folding machine is able to move 5 flip folders. This Fuzzy-PD control system is able to improve the system response when there is a load, where the difference is only 7.73% from the no load condition. In addition, to implement this flip folder, a stochastic based method (ARX) is also applied on this system so it can be simulated directly. The simulation results from this folding machine model have a time constant of 0.510s, rise time of 1.501s, settling time of 1.5320s and delay time of 0.353s.

“…[10][11][12] Due to the larger distance between the robots' foot and roll shaft, in the same foot end force, the required driving torque is larger. [13][14][15] In order to obtain the required driving torque, it can be realized by increasing the oil supply pressure, increasing the effective area of the hydraulic cylinder and adopting multi-cylinder parallel connection and other ways. The limitation of hydraulic components makes the oil supply pressure of hydraulic system cannot be infinitely increased.…”

In the article, a heavy-duty quadruped robot was designed. A parallel cylinder transmission scheme for the heavy load torque of the hip joint of heavy-duty hydraulic quadruped robot is proposed, the mathematical model of the parallel cylinder system is derived, the model characteristics of the parallel cylinder system are analyzed, the characteristics of internal force and joint control of parallel cylinders are considered, the force/position hybrid control of parallel cylinder is proposed to eliminate the internal forces and realize the requirement of joint control and the force/position control is decoupled by the design of the force and position signal. According to the characteristics of the servo cylinder force control model, the flow compensation and speed compensation are introduced, the minimum control synthesis controller is used to control the servo cylinder force and the proportional integral controller is applied to control the position of servo cylinder. The compound control strategy is analyzed on the table of parallel cylinder, and the experimental results show that the amplitude attenuation and phase lag of position and force are less than 10% and 18 , respectively, and the efficiency of the proposed control strategy is verified. The research results of this article will be widely used in many fields of robot control in the future.
