Design of Linear Quadratic Optimal Regulator for Nanopositioning System
Abstract: One of the most important requirement of nanotechnology is precision control and manipulation of devices and materials at nanoscale i.e., nanopositioning. In this paper, open loop characteristics of the non minimum phase nanopositioning system such as poles and zeros location, controllability, observability are investigated. To improve the system characteristics feedback controllers are used. The key of the controller is to design a system with good time response characteristics as well …

LQR based Optimal Verses Classical PID Controller for the Longitudinal Dynamics of an Aircraft
Abstract: The main objective of the present work is to investigate the design aspect of optimal controller for the pitch control of an aircraft. In this paper Linear Quadratic Regulator (LQR) for optimal stability analysis of closed loop attitude control system of an aircraft is presented. The result of proposed controller is compared with classical proportional integral derivative (PID) controller. It is observed that the optimal control technique outperforms the PID …

Modeling, Analysis and LQR Control of an EV Differential using IPMSM
Abstract: Recently, the mechanical differential (MD) of vehicle has been replaced by electronic differential (ED) by means of electric motor. Electronic differential ensures dynamic and robust control of the vehicle behavior. The ED has been designed for an electrical vehicle (EV) based on IPMSM due to its some inherent advantageous features. The design of speed controller of an IPMSM mainly depends on its mathematical model. The mathematical model based speed controller …

LQR-Based Optimal Control of Inverted Pendulum System with State Estimation and Stability Analysis
Abstract: The inverted pendulum on a cart is a canonical benchmark problem in control systems engineering, capturing the essential challenges of stabilizing an inherently unstable, underactuated, and nonlinear plant. Classical Proportional-Integral-Derivative (PID) controllers, while widely employed in industrial practice, exhibit fundamental performance limitations when applied to such systems, primarily due to their inability to account for multivariable coupling, process noise, and the absence of a systematic optimization framework. This paper presents …
