“…In data-driven model-based techniques, this knowledge is achieved via experiments, by artificially injecting the major faults and measuring the system response during and after the fault [20,28,29,42,43]. This method provides more accurate predictions, but rigging costs are often prohibitive and the FDI strongly depends on tested conditions.…”

“…Many research efforts have been and are made to protect EMAs from jamming, by applying both prognostic and diagnostic monitoring methods, aiming at anticipating (i.e., avoiding), or detecting and isolating the fault, respectively. The prognostic solution, though potentially overwhelming [27][28][29][30], is nowadays far from being applicable to airworthy systems, so that diagnostic approaches are typically preferred [31,32].…”

The work deals with the development of deterministic model-based condition-monitoring algorithms for an electromechanical flight control actuator with fault-tolerant architecture, in which two permanent magnets synchronous motors are coupled with differential ball screws in speed-summing paradigm, so that the system can operate even after a motor fault, an inverter fault or a mechanical jamming. To demonstrate the potential applicability of the system for safety-critical aerospace applications, the failure transients related to major fault modes have to be characterised and analysed. By focusing the attention to jamming faults, a detailed nonlinear model of the actuator is developed from physical first principles and experimentally validated in both time and frequency domains for normal condition and with different types of jamming. The validated model is then used to design the condition-monitoring algorithms and to characterize the system failure transient, by simulating mechanical blocks in different locations of the transmission. The operability after the fault, obtained via fault-tolerant control strategy and position regulator reconfiguration, is also verified, by highlighting and discussing possible enhancements and criticalities.

“…Electro-mechanical actuator is a kind of green linear actuator with high control accuracy and energy efficiency, widely used by aerospace, precision machining, robots, and simulation platforms [18]- [20]. Compared with the hydraulic cylinder drive, the electro-mechanical actuator does not need to control the load movement through the throttling effect of the valve, and there is no throttling loss [21].…”

A Novel Electro-Hydraulic Compound Driving System With Potential Energy Regeneration Capability for Lifting Device

et al. 2022

In order to realize the high energy efficiency and high performance motion control of the lifting device of construction machinery, this paper proposes an electro-hydraulic compound driving system that can regenerate the potential energy. In this new system, the high-power density combination of hydraulic cylinder with accumulator is used to balance the self-weight of the lifting device and recycle the gravitational potential energy directly. The green electro-mechanical actuator with high energy efficiency and control performance is used to control the motion of the lifting device. In addition, control valves are added to dynamically adjust the pressure of the two chambers of the hydraulic cylinder and increase the stiffness of the hydraulic system, which can restrain the impact of acceleration and deceleration of large inertia lifting device and rapid charging and discharging of accumulator on electro-mechanical actuator. Finally, a typical construction machinery excavator is structurally modified to build a test platform. The test results show that, under the same working conditions, the proposed electro-hydraulic compound driving system can further reduce energy consumption by 31% and reduce peak power by 15% than that of the high energy efficiency three-chamber hydraulic cylinder driving system with potential energy regeneration. The boom runs smoothly, and the velocity overshoot and fluctuation time are significantly reduced, realizing high performance driving of the lifting device with low energy consumption. The research results also have broad application prospects in missile erection devices, cranes, presses, and other equipment.
