Practical implementation of the program controlling the movement of the excavator’s working tool (including the use of satellite navigation system) imposes stringent requirements on the dynamic and static accuracy of automatic control systems for the hydraulic excavator’s operating mechanisms, in conditions of non-stationary parameters of these mechanisms as control objects. The authors describe the effective solution of this problem by implementing structural synthesis of each servo hydraulic drive as a multi-loop system with one measured coordinate (MLSOMC). The EO-4121 excavator with four hydraulic drives (rotary platform, boom, arm and ladle) was used as an example to demonstrate that the implementation of three circuits in the multi-loop system with one measured coordinate in each of these drives with typical PID-controllers allows to ensure the robustness of the ACS for known uncertainties, as well as the required rates of control quality in static and dynamic modes.



Field Programmable Gate Arrays are recently replacing general purpose microcontrollers in implementation of digital control systems. This paper includes the proposal of implementing complex controller structures in a Field Programmable Gate Array (FPGA). Till recent, PID controllers are implemented in FPGA Platform. PID controllers are simple, reliable, versatile feedback mechanisms used in most control systems. To reduce various undesirable effects on the output such as overshoot, some variants in the conventional PID controllers, such as the I-PD and IMC are also used. Here all these control controller structures are implemented in MATLAB, compared for best performance and run in the FPGA.

Abstract The problem of designing conventional controllers is a major concern in both academia and industry. The paper presents the implementation of a Matlab interface that facilitates the students’ understanding of the closed-loop control systems operation. There are four operating scenarios: with controllers for which the parameters are known; with controllers for which parameters are determined experimentally; with proportional controllers and additional poles/zeros introduction; with proportional controllers and serial compensator.

Abstract The paper deals with an analysis of automatic control system with continuous and discrete PID controllers. A method of tuning the parameters of the continuous controller is presented, which is optimal according to the ITAE criterion. The behavior of control systems with discrete controllers whose parameters were tuned using the mentioned method are described. The impact of changes in the sampling period of controlled signal on the control quality is shown. Changes of the values of optimal parameters of discrete PID controllers in relation to changes of the sampling rate of controlled signal are characterized.
