Answer the question using human knowledge on urgently basis please 178. Describe the significance of the Separation Principle in designing digital state observers for real-time applications.
Added by Noelia H.
Step 1
It states that the design of the controller and the state observer can be carried out independently. This principle is particularly relevant in the context of digital state observers used in real-time applications. Show more…

[25pts] Consider the feedback system shown in Fig. 1, where R(s) is the reference input, Y(s) the output, and W(s) the external disturbance. (a) Obtain the transfer function of the system (from R(s) to Y(s)). (b) Given K=0.25, determine the step response y(t) of the system. (Assume that the disturbance is absent.) [25pts] Consider the control system of Fig. 1 again. (a) Determine the system type with respect to disturbance. (b) Determine the steady-state response yss if u(t)=6, t≥0 and w(t)=0.5, t≥0. [25pts] Consider the control system of Fig. 2 again. (a) Sketch the root-locus of the system with respect to parameter K. (b) Design a value of K such that the step response of the system has a settling time of 1.5 seconds.

1. Consider that a digital control system is described by the state equation x(k + 1) = [[1, -2], [1, -1]]x(k) + [[1, 0], [0, -1]]u(k) y(k) = [1 0]x(k) I. Is this system stable? II. Determine the controllability and observability of this system 2. Consider that a digital control system is described by the state equation x(k + 1) = [[1, -2, 0], [3, 2, 1], [-1, 1, 4]]x(k) + [[1, 0], [-1, 1], [0, 1]]u(k) y(k) = [1 0 0]x(k) I. Is this system stable? II. Determine the controllability and observability of this system 3. The following Figure shows a stick-balancing system in which the objective is to control the attitude of the stick with the force u(t) applied to the car. The force u(t) is sampled and is described by u(t) = u(kT), kT ≤ t < (k + 1)T Where T is the sampling period. The linearized equations that approximate the motion of the stick are ̈θ(t) = θ(t) + u(t) ̈y(t) = θ(t) - u(t) Let the state variables be defined as x₁(t) = θ(t), x₂(t) = ̇θ(t), x₃(t) = y(t), and x₄(t) = ̇y(t) I. Discretize the system equations and express the state equations in the following form x(k + 1) = Ax(k) + Bu(k) II. For T=1 sec determine if the discrete-data system of part (I) is stable, and completely state controllable. You can use MATLAB for solving and verifying your results.
