Background and Objectives: The annual Accreditation Council for Graduate Medical Education (ACGME) survey evaluates numerous variables, including resident satisfaction with the training program. We postulated that an anonymous system allowing residents to regularly express and discuss concerns would result in higher ACGME survey scores in areas pertaining to program satisfaction. Methods: One family medicine residency program implemented a process of quarterly anonymous closed-loop resident feedback and discussion in academic year 2012-2013. Data were tracked longitudinally from the 2011-2019 annual ACGME resident surveys, using academic year 2011-2012 as a baseline control. Results: For the survey item “Satisfied that evaluations of program are confidential,” years 2013-2014, 2014-2015, and 2018-2019 showed a significantly higher change from baseline. For “Satisfied that program uses evaluations to improve,” year 2018-2019 had a significantly higher percentage change from baseline. For “Satisfied with process to deal with problems and concerns,” year 2018-2019 showed significantly higher change. For “Residents can raise concerns without fear,” years 2013-2014 and 2018-2019 saw significantly higher changes. Conclusions: These results suggest that this feedback process is perceived by residents as both confidential and promoting a culture of safety in providing feedback. Smaller changes were seen in residents’ belief that the program uses evaluations to improve, and in satisfaction with the process to deal with problems and concerns.

Target Path

It is very important to simulate driver's manipulation for people - car - road closed loop simulation system. In this paper, the driver model is divided into two parts, linear vehicle model is used to simulate the driver's driving experience, and closed-loop feedback is used to characterize the driver's emergency feedback. The lateral acceleration of vehicle is used as feedback in closed loop control. Simulation results show that the smaller lateral acceleration requires the less closed-loop feedback control. The driver model can accurately track the target path, which can be used to simulate the manipulation of the driver. The driver model can be used for people - car - road closed loop simulation to evaluate vehicle handling stability.

Dry Clutch

The closed loop feedback control system of an Automated Manual Transmission (AMT) electro-pneumatic clutch actuator is used for intelligent real time condition monitoring, enhanced diagnostics and prognostic health management of the dry clutch system, by integrating with the existing gearbox prognostics observer. The real-time sensor data of the clutch actuator piston position is analyzed for monitoring the condition of the clutch system. Original parameters of the new clutch are stored in the Electrically Erasable Programmable Read-only Memory (EEPROM) of the AMT controller and the real-time data is used by the observer for assessing the degradation/wear of the frictional clutch parts. Also, clutch slip during torque transmission is monitored, using the engine speed and the gearbox input shaft speed from Controller Area Network (CAN). Condition monitoring of clutch system provides enhanced prognostic functionality for AMT system which ensures consistent clutch performance, gear shift quality and timely warning for recalibration, repair and/or replacement of the critical wear and tear parts. Also, systematic analysis of the monitored data provides an accurate diagnosis of a developing fault. Thus, with the advanced control systems in place for AMT, a closed loop feedback based condition monitoring system is modelled for improved diagnostics and prognostics of AMT clutch system.

The Stability

The study presents model-based mechanism of nonlinear cutting tool vibration in turning process and the strategy of improving cutting process stability by suppressing machine tool vibration. The approach used is based on the closed-loop feedback control system with the help of electro–magneto–rheological damper. A machine tool vibration signal generated by an accelerometer is fed back to the coil of a damper after suitable amplification. The damper, attached under the tool holder, generates counter forces to suppress the vibration after being excited by the signal in terms of current. The study also discusses the use of transfer function approach for the development of a mathematical model and adaptively controlling the process dynamics of the turning process. The purpose of developing such mechanism is to stabilize the machining process with respect to the dynamic uncut chip thickness responsible for the type-II regenerative effect. The state-space model used in this study successfully checked the adequacy of the model through controllability and observability matrices. The eigenvalue and eigenvector have confirmed the stability of the system more accurately. The characteristic of the stability lobe chart is discussed for the present model-based mechanism.
