In order to lower cost and complexity, our first choice is a linear controller. To this end, we linearize the mathematical model of Quasi- moro around one of the equilibrium states, x» = 0g, with Og denoting the 6-D zero vector, which yields [19]

where aj and a; are defined as [3.452 3.452 -—20.720]" and [0 0 1]7, respectively. where x, is the reduced state vector, i.e., a vector with some of the components of x, while M,. and K, are the gain matrices for reference input tracking and the state-feedback matrix, respectively. Therefore, for controller design, we shall refer to a reduced state-space model governed by the matrices
