The final structure takes the form of PD controller with P-term as the main controller and D-term as supplementary to accelerate response speed and to improve the control stability. The PD controller is embedded in a rule-based coordinated ramp metering strategy for performance evaluation. A ...
In order to provide practical guidelines for the design of PD controllers we describe the stability regions in the gains-parameter space using a geometric approach. Illustrative examples complete the presentation.关键词: haptics Time-delay Proportional-Derivative (PD) control distributed time-delays ...

Based on the obtained model, a new control scheme that incorporates six Proportional-Derivative (PD) controllers is proposed for the attitudes (roll (φ), pitch (θ), yaw (ψ)) and the positions (x, y, z) of the aircraft. Then, intelligent Particle Swarm Optimization (PSO) and ...
Many robot manipulators use proportional-derivative (PD) control with gravity and friction compensations, and the gravity and friction models are needed. Intelligent control has dramatically changed the face of industrial control engineering. The intelligent compensation for PD/PID control has developed ...

In computer animation, the proportional-derivative (PD) controller is a common technique for tracking characters' motion. A new formulation of the PD controller-stable PD (SPD)-allows arbitrarily high gains, even at large time steps. The key is to determine joint forces and torques while taking...
It is powered by a brushed DC motor, which is widely available in developing regions, and utilizes a modified proportional-derivative (PD) control algorithm to simulate both harmonic and real earthquake motions. Using this design, displacements up to ±150 mm and accelerations up to 1g were ...
Based on proportional‐integral‐derivative (PID)/PD controls, we in the article investigate the tracking problem of a class of second‐order time‐varying switched nonlinear systems. To start with, for tracking a given point under arbitrary switching signals, we propose a sufficient condition about...
However, the PD control method is challengable because the state signals of singular systems are not always measurable. Therefore, a novel fuzzy observer is designed to ensure the existence of estimated states. For the observer-based PD control issue, some sufficient stability conditions are derived...
