Feedback control is a method of regulating a process by comparing the actual output with a desired set point and adjusting the input accordingly. It is widely used in plant operations to maintain ...

Learn how feedback can enhance the stability, accuracy, and performance of control systems, and what are the types, loops, characteristics, benefits, and challenges of feedback. Sign in to view ...

The open-loop control system is a continuous control system that provides no feedback from its output. The control process, therefore, is only affected by the system’s input. Traditionally, electrical ...

Abstract: An adaptive output feedback nonlinear control scheme is presented for a pH process, which is difficult to control due to the nonlinearities and uncertainties. A nonlinear controller is ...

As the technology developed in the 1970s and 1980s, more complex approaches and strategies developed, involving multiple inputs and outputs with more complex models. Eventually, multivariable, ...

This work develops a control strategy to handle coupling effects between the level and pH for a pH process with multiple titrant streams. The feedback controller is formulated based on a nonlinear ...

This article presents an input-and-measurement event-triggered output-feedback chattering reduction control for microelectromechanical system (MEMS) gyroscopes. To realize online estimation with ...

Mechanical control systems (staplers, car windows) use parts for movement/force control. They include input, process, and output. Types of motion: linear, rotary, reciprocating, oscillating.
