So for any given system, if we simply multiply it's transfer function by 1/s (which means putting an integrator in cascade or series with the system), the output defined by the inverse Laplace Transform of that result will be the step response It's that simple..
Is a control system whose step response is 0.5 1 e 2t cascaded?
Solution: Laplace transform is the transformation that transforms the time domain into frequency domain and of both the cascaded systems are 1/(s+1)(s+2). A control system whose step response is -0.5(1+e-2t) is cascaded to an Therefore, the correct answer is option 'A': 1/(s2)(s1)..
What is step function in control system?
The step function is one of most useful functions in MATLAB for control design. Given a system representation, the response to a step input can be immediately plotted, without need to actually solve for the time response analytically..
What is the step response of a control system?
It is how a system responds to a step input. So, we can input a unit step function into a system—that's when the input changes from zero to one in a very short period of time—and we can measure the behavior of the system that results from it. That behavior is the unit step response..
What is the system response to a step input?
Definition: Step Response The step response of a system is defined as its response to a unit-step input, u(t), or u(s)=1s. Let G(s) describe the system transfer function; then, the unit-step response is obtained as: y(s)=G(s)1s. Its inverse Laplace transform leads to: y(t)=L−1[G(s)s]..
Solution: Laplace transform is the transformation that transforms the time domain into frequency domain and of both the cascaded systems are 1/(s+1)(s+2). A control system whose step response is -0.5(1+e-2t) is cascaded to an Therefore, the correct answer is option 'A': 1/(s2)(s1).
The response of a system (with all initial conditions equal to zero at t=0-, i.e., a zero state response) to the unit step input is called the unit step response. If the problem you are trying to solve also has initial conditions you need to include a zero input response in order to obtain the complete response.
The step function is one of most useful functions in MATLAB for control design. Given a system representation, the response to a step input can be immediately plotted, without need to actually solve for the time response analytically.

Time behavior of a system controlled by Heaviside step functions
The step response of a system in a given initial state consists of the time evolution of its outputs when its control inputs are Heaviside step functions. In electronic engineering and control theory, step response is the time behaviour of the outputs of a general system when its inputs change from zero to one in a very short time. The concept can be extended to the abstract mathematical notion of a dynamical system using an evolution parameter.
