Clutch-to-clutch shift technology is a key enabler for fast and smooth gear shift process for multi gear transmissions. However, conventional hydraulic actuation systems for clutches have drawbacks of low efficiency, oil leakage and inadequate robustness. Electromechanical devices offer potential alternative actuators. In this paper, a novel motor driven wedge-based clutch actuator, featuring self-reinforcement, is proposed. The design concept and physical structure are thoroughly described. Dynamic models for the actuation system and vehicle powertrain are validated by experiments. Upshift and downshift processes at different engine throttle openings, clutch clearances and friction coefficients are discussed. The results show that, the self-reinforcement ratio is tested as 9.6; at the same time, the shift quality is comparable to that of the conventional hydraulic actuated clutch in automatic transmissions in terms of the shift duration (about 1 s) and vehicle jerk (\10 m/s 3). Taking advantage of fast response of the actuation DC motor, the wedge-based actuator is robust dealing with uncertain clutch clearance and friction coefficient. Therefore, the wedge-based clutch actuator has potential to provide acceptable performance for clutch-to-clutch shift.

“…Through experimental studies, Canadus de Wit et al analyzed the impact of loadtype change on the friction model and designed an adaptive regulating controller for the model [20], [21], thus putting forward a bristle model to identify the parameters of the motor servo control system. With regard to Bosch GPA-S electromechanical actuator [23], Kebairi et al put forward a series of friction modeling and identification methods. On the basis of a cascaded structure, Luc Le-Tien and Alin Albu-Schaffer put forward a robust adaptive control scheme flexible-joint robots taking a full state feedback controller with integrator terms such as inner control loop, and the computed torque as outer control loop.…”

In the research of various energy technologies, the direct-drive volume control flange-type rotary vane steering gear (DDVC-FRVSG) has become a promising component for controlling the course and posture of a vessel because of its superior energy-saving performance. However, nonlinear friction limits the ability of the DDVC-FRVSG to satisfy the efficient energy requirements of the vessel. This study proposes compensation methods to suppress nonlinear friction, such that the rudder can be efficiently controlled. Based on the principle of the DDVC-FRVSG, we establish a mathematical model and transfer function of the steering gear system along with a mathematical model of the impact of nonlinear friction on the rudder system. A friction model-based method using the integral back-stepping adaptive control strategy is proposed to suppress nonlinear friction, and both the models are studied theoretically and through simulation. Taking the no-compensation state as a benchmark, our measured results by prototype testing reveal that the method can compensate for nonlinear friction, achieving up to 73.08 % better performance on average and reducing the output power of the driving motor by 36.39 % on average. The findings of this research will contribute to the energy-saving performance and efficient energy requirement of the DDVC-FRVSG system.

Water quality is an important factor in creating the conditions needed for survival in a pond. The purpose of the research is to design a control system capable of maintaining the required water temperature and pH, as vital parameters of water quality influences for shrimp growth in a miniature pond using a Zelio logic smart relay device. The water condition was controlled with the smart relay by employing the analog and digital inputs, and digital outputs. The control system was made up of two analog sensors for temperature and pH meters. An Arduino Uno microcontroller interfacing between a pH sensor and the Zelio, and the temperature and pH data charts and saved Excel files were the new proposed solutions. According to the results, the utilization of the aerator and water pump as a control method proved to be an effective procedure for keeping the temperature at around 25.4⁰C. This control system produced the new temperature condition, which was within the specified range of 25-32 o C. Also, the pH was effectively maintained at the required range of 7.0-8.0. The system worked according to these parameters-the pH above 7.0, and the temperature maintained below 32 o C, which could represent the required conditions of the water from the shrimp embankment.
