Autonomous underwater vehicles (AUV) are used in many applications like mining, aquaculture and military applications. AUV is highly nonlinear system; modeling and controller performance is challenging issue for the researchers. In this paper a linear quadratic regulator (LQR) and proportional integral derivative (PID) controllers are designed for the depth control system of AUV. These controll...

A was flown in an facility made track...

This review focuses on manipulator control systems, which are systems that the movement of manipulators, a type robot programmed to move in specific ways. The send commands actuators (such as motors or pneumatic cylinders) based input from sensors position force sensors) manipulator's joints. Manipulator have wide range applications industries such robotics, industrial automation, and medical s...

Various guidance laws have been exploited with different design concepts over the years [2]. Currently, the most popular terminal guidance laws, as defined by Locke [1], involve Line-Of-Sight (LOS) guidance, LOS rate guidance and other advanced guidance such as proportional navigation guidance [1], Augmented Proportional Navigation Guidance (APNG) [3], optimal guidance law based on the linear q...

In this paper, state-derivative and especially output-derivative feedbacks for linear time-invariant systems are derived using control approach similar to linear quadratic regulator (LQR). The optimal feedback gain matrices are derived for the desired performance. This problem is always solvable for any controllable system if the open-loop system matrix is nonsingular. Explicit expression of th...

Road surface roughness is the leading cause of vehicle oscillation. The suspension system used to dampen these oscillations. active equipped with a hydraulic actuator more efficient than passive one.

In this article, author mentioned three dynamic commonly simulate oscillations: quarter-dynamic mod...

Based on recently developed sufficient conditions for stability of polynomial matrices, an LMI technique is described to perform robust pole placement by proportional-derivative feedback on second-order linear systems affected by polytopic or norm-bounded uncertainty. As illustrated by several numerical examples, at the core of the approach is the choice of a nominal, or central quadratic polyn...
