This study presents a force control approach for an EHA system using a combination of a feedforward-based PID (FPID) controller and a grey predictor (GP), shortened as grey predictor-based feedforward PID Controller (GPFPID). The FPID controller is used to drive the system to desired targets. Meanwhile, the GP predictor takes part in estimating the output in the near future to optimize the controller parameters in advance and to create a compensating control signal corresponding to the system perturbations, consequently, improving the control performance.

This paper gives an illustration of using the computational fluid dynamics approach to investigate the movement of the solution inside the hand-washing chamber. The numerical results obtained from the numerical simulation demonstrate the hydrodynamic values, streamlines, and density of the solution. The ability to predict the handwashing chamber's hydraulic and cleaning performance efficiencies is essential for evaluating the operability and improving the further design.

In the event of a complete Station Blackout (SBO) of a CANDU reactor, the current safety practice is to initiate depressurization early in the transient once a lack of power has been declared. This requires operator actions to manually open the main steam safety valves (MSSVs) on the secondary side initiating a crash-cool procedure.
