This paper investigates the performance evaluation of two state feedback controllers. Pole Placement (PP) and Linear Quadratic Regulator (LQR). The two controllers are designed for a Mass-Spring-Damper (MSD) system found in numerous applications to stabilize the MSD system performance and minimize the position tracking error of the system output. The state space model of the MSD syste... https://hollandscountryclothinges.shop/product-category/first-aid-kits/
