An adaptive deep reinforcement learning approach for MIMO PID control of mobile robots.
ISA transactions, 2020Intelligent control systems are being developed for the control of plants with complex dynamics. However, the simplicity of the PID (proportional-integrative-derivative) controller makes it still widely used in industrial applications and robotics.

Annual Reviews in Control, 2000
Abstract The history of pneumatic PID controllers covering the invention of the flapper-nozzle amplifier, the addition of negative feed back to the amplifier and the incorporation of rest (integral) and pre-act (derivative) actions is described. The transition of the controller from a special purpose unit to a robust, reliable, widely used unit; the ...

2010 International Conference on Machine Learning and Cybernetics, 2010
This paper proposes an adaptive proportional-integral-derivative (PID) controller which integrates the fuzzy sets with the Cerebella Model Articulation Controller (CMAC). Three gain parameters of PID controller, constructed by three fuzzy CMAC (FCMAC) models, are real-time modified in the sense of adaptation to solve the tracking control problem of a ...

Simulation of hydraulic transplanting robot control system based on fuzzy PID controller
, 2020At present, there is a problem that the output accuracy of the transplanting manipulator is low due to interference from external factors. To solve the problem of low output accuracy of the transplanting manipulator caused by the interference of external

IFAC Proceedings Volumes, 1982
Abstract The appearance in the market of the first PID self-tuning (PID/ST) controller (see Cont. Eng. Oct. 1981) reflects the necessity of the industry to satisfy increasingly stringent control objectives which can only be attained with adaptive algorithms. The newer trends of the relatively mature adaptive control theory i.e.

PID or Not PID? That Is the Question.
Adolescent medicine (Philadelphia, Pa.)A 14-year-old female was seen for acute abdominal, back, and flank pain, accompanied with dysuria, increased frequency of urination, nausea, and decreased appetite. After an initial diagnosis of pyelonephritis, a presumptive diagnosis of pelvic inflammatory disease (PID) was made. The cervical culture was positive for Chlamydia trachomatis and a pelvic

Conservative Management of PID
Annals of the New York Academy of Sciences, 2000Abstract: The goals in the management of pelvic inflammatory disease (PID) are not only treatment of the infection and prevention of immediate complications, but also prevention of its long‐term consequences. There are criteria for hospitalization, but patients who do not meet them can be safely treated as outpatients.

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

Simple PID Tuning and PID Closed-Loop Simulation
1983 American Control Conference, 1983This work presents simple tuning relationships for PID controllers, both continuous (analog or microprocessor) and discrete (computer), that have proven effective for processes with significant dead time. A dynamic simulator package that has been used effectively for PID controller tuning experimentation, verification, and engineer training is ...
