Common types of Robot Control Algorithm

There are various types of robot control algorithm used in robotics, each with its own strengths, weaknesses, and suitable applications. Here are some widely used types:

Proportional-Integral-Derivative (PID) Controller: This is a widely used robot control algorithm in engineering and automation systems. It is designed to regulate and stabilize the output of a system by continuously adjusting a control variable based on the error between the desired setpoint and the actual process variable.
Fuzzy logic controller (FLC): FLC uses fuzzy logic to make decisions and control processes. Fuzzy logic is an approach to variable processing that allows for multiple possible truth values to be processed through the same variable. Fuzzy logic attempts to solve problems with an open, imprecise spectrum of data and heuristics that makes it possible to obtain an array of accurate conclusions.
Neural network controller (NNC): The neural network-based control of mobile robots is usual to work with kinematic models of automated mobile robot to obtain stable motion control laws for trajectory following or goal reaching.
Adaptive controller: This is a type of control system that can adjust its parameters or behavior in real-time to adapt to changes in the system or environment it is controlling. The purpose of an adaptive controller is to improve control performance and maintain stability even in the presence of uncertainties, variations, or disturbances.
Robust controller: This is a type of control system design that is specifically designed to achieve robust performance when tuning control systems to high-level design requirements you specify, such as reference tracking, disturbance rejection, stability margins, and loop shapes.

The choice of robot control algorithm depends on the specific requirements of the task, the robot’s dynamics, available sensor information, and the desired monitor robot activities.
