On a Modification of the PID Controller
Dynamics and Control, 1997The paper considers the controlled system \[ x^{(n)}+ a_nx^{(n-1)}+ \cdots + a_2x' +a_1x =u(t) \] and the finite-memory controller \[ u= -c_1 \bigl(x(t) -x_d(t)\bigr)-c_2 \bigl(x'(t) -x_d'(t) \bigr)- c_3\int^t_{t- \sigma} \bigl(x (\tau)- x_d(\tau) \bigr)d \tau \] \(x_d(t)\) being the reference signal. This controller is shown to have several advantages

A Reconfigurable PID Controller
2018We survey the Proportional-Integral-Derivative (PID) controller variants and we switch them in runtime via reconfiguration, as the control requirements change. Depending on the PID variant, e.g. P, I, PI, PD, PID, PI-PD, the involved computations to produce the control output are different.

ISA Transactions, 2007
In this paper, an index for measuring fragility of proportional integral derivative (PID) controllers is proposed. This index relates the losses of robustness of the control loop when controller parameters change, to the nominal robustness of the control loop. Furthermore, it defines when a PID controller is fragile, nonfragile or resilient.

Spiking Neural PID Controllers
2011A PID controller is a simple and general-purpose way of providing responsive control of dynamic systems with reduced overshoot and oscillation. Spiking neural networks offer some advantages for dynamic systems control, including an ability to adapt, but it is not obvious how to alter such a control network's parameters to shape its response curve.

Comparison of PID control and PPI control
42nd IEEE International Conference on Decision and Control (IEEE Cat. No.03CH37475), 2004Predictive PI (PPI) control form, capable of time delay compensation, has been put forward recently. This control algorithm is essentially a PI controller with enhanced derivative action, and is not only suitable for long time delay process, but also of simple structure and excellent robust stability.

PID Controller for Idle Speed Control
2013 UKSim 15th International Conference on Computer Modelling and Simulation, 2013The performance comparison of PID controllers for idle speed control internal combustion engine (ICE) is presented in this paper. There are three methods of PID tuning applied: heuristic tuning, self-tuning by pole placement, and also iterative learning algorithm (ILA).

2016 8th International Conference on Electronics, Computers and Artificial Intelligence (ECAI), 2016
A controller is the most important part of an automatic control system. Its main purpose is to receive the signals from a transmitter and to compare it with a reference value. Depending on the error the controller sends a control signal to an actuator, so that the controlled variable to be equal with the reference value.

Enhanced PID controller design
Proceedings. 1991 IEEE International Conference on Robotics and Automation, 2002A method is presented for designing proportional-integral-differential (PID) controller for single-input, single-output (SISO) systems and is subsequently extended to multiple-input, multiple-output (MIMO) systems of a certain class. All systems are assumed to be linear time-invariant systems and to employ unity output feedback.

Frequencial adaptive PID-controller
1999 European Control Conference (ECC), 1999Algorithm of adaptive PID-controller for plant with unknown coefficients in the presence of unknown-but-bounded disturbance is derived. It makes use of a sufficient small test signal. Adaptation process consists of intervals on which a plant and closed-loop system are identified on the base of finite-frequency identification technique.
