This paper presents the implementation of HDE algorithm for Concurrent Relay-PID (CRPID) controller for motor position servo systems. CRPID is composed of a deadband relay subcontroller which improves the transient performance and the parallel PID subcontroller which improves the steady state performance of the system. Controller is implemented using modern heuristic tuning techniques which are...

This study offers a thorough examination of the zero voltage switching (ZVS) operation range and deadband conditions for bidirectional DC-DC converter with phase shift control, featuring dual H-bridge. The analysis considers soft DAB converter, accounting impact headband ZVS capacitor. By applying differential equation circuit during time, sufficient constraint input output bridges can be calcu...

Electronic olfaction can help detect and localize harmful gases pollutants, but the turbulence of natural environment presents a particular challenge: odor encounters are intermittent, an effective electronic nose must therefore be able to resolve short pulses. The slow responses widely used metal oxide (MOX) gas sensors complicate task. Here, we combine high-resolution data acquisition with pr...

This papers deals with the emergency control of Load Tap Changers (LTCs) to face low transmission voltages or voltage instability situations. The proposed simple control logic consists in reverting the tap movements once the voltage at a monitored transmission bus falls below some threshold. A deadband on this voltage allows the system to settle down in between the normal and reverse logic mode...

This paper presents a novel disturbance observer-based adaptive neural network control for hydraulic knee exoskeleton with valve deadband and output constraint. Adaptive networks are employed to approximate the unknown nonlinearities of actuator, i.e., unmodeled dynamics caused by leakage. A observer is designed integrated into controller compensate external equivalent interactive force acted o...

Oscillations in control loops lead to poor controller performance. Stiction in control valves is one of the major causes of such oscillations. Therefore, the correct diagnosis of stiction is important. There are several methods for detecting stiction, but quantification of stiction still remains a challenge. Two parameters are used to model the stiction phenomenon successfully, namely, deadband...

Multimodal telepresence and teleaction systems enable a human operator to perform in remote environments through a telerobot and a communication network. The focus of this article is on the networked haptic (force feedback) control system with the key challenges of stability and transparency. Transparency is achieved if the human cannot distinguish between direct and teleinteraction. Human perc...
