1: Introduction
The purpose of this laboratory is to observe the behavior of an inverted pendulum, an
unstable, nonlinear system. We were tasked with simulating the integration of a
proportional-plus-derivative(PD) controller design modeled using Simulink and MATLAB
to study its ability to stabilize the inverted pendulum system based on various factors.

In this problem, you will have to first create a Python function called twobody_dynamics_first_order_EoMS. Given a time t and a
state vector X, this function will return the derivatives of the state vector. Mathematically, this means you are computing X using
some dynamics equation X = f(t, X).
Once you have this function in Python, you can solve the differential equations it contains by using solve_ivp. The command will be
similar to, but not necessarily exactly, what is shown below:
solve_ivp(simple_pendulum_first_order_EoMS, t_span, initial_conditions, args=constants, rtol
1e-8,
atol 1e-8)
which integrates the differential equations of motion to give us solutions to the states (i.e., position and velocity of a satellite). In the
above, t_span contains the initial time to and final time tƒ and it will compute the solution at every instant of time (you will define this
later in Problem 1.3 below).
The integration is done with initial state vector Xo which defines the initial position…

5. Figure 4 shows a pile driver that is used to drive piles into soil to provide foundation support
for buildings. Two major components of a pile driver are a pile and a weight. The pile is in
the form of a long rod going into the soil. The weight is to impact the pile at the top with
an impulsive force, thus driving the pile into the soil. Figure 5 shows a first-order model of
the pile in the soil. The impulsive force produced by the weight is f(t). The resistance of the
soil is modeled via a viscous damping coefficient. b. The weight of the pile is balanced by the
normal forces in the soil, so it does not need to be considered. In addition, the elasticity of
the soil is ignored. Let z(t) and v(t) be the downward displacement and velocity of the pile,
respectively. The equation of motion governing the pile velocity v(t) is

A velocity of a vehicle is required to be controlled and maintained constant even if there are disturbances because of wind, or road surface variations. The forces that are applied on the vehicle are the engine force (u), damping/resistive force (b*v) that opposing the motion, and inertial force (m*a). A simplified model is shown in the free body diagram below.
From the free body diagram, the ordinary differential equation of the vehicle is:
m * dv(t)/ dt + bv(t) = u (t)
Where:
v (m/s) is the velocity of the vehicle,
b [Ns/m] is the damping coefficient,
m [kg] is the vehicle mass,
u [N] is the engine force.
Question:
Assume that the vehicle initially starts from zero velocity and zero acceleration. Then, (Note that the velocity (v) is the output and the force (w) is the input to the system):

Given a time t and a state vector X, this function will return the derivatives of the state vector. Mathematically, this means you are computing X using some dynamics equation X = f(t, X). Once you have this function in Python, you can solve the differential equations it contains by using solve_ivp. The command will be similar to, but not necessarily exactly, what is shown below: solve_ivp(simple_pendulum_first_order_EoMS, t_span, initial_conditions, args=constants, rtol 1e-8, atol 1e-8) which integrates the differential equations of motion to give us solutions to the states (i.e., position and velocity of a satellite). In the above, t_span contains the initial time to and final time tƒ and it will compute the solution at every instant of time (you will define this later in Problem 1.3 below). The integration is done with initial state vector Xo which defines the initial position…arrow_forward11. Consider a system that can be modeled as shown. The input x in (t) is a prescribed motion at the right end of spring k 2. Find X(s) the system transfer function Xeq(s)* m k₂ ww Xin The values of the parameters are m= 30 kg, k ₁=700 N/m, k 2= 1300 N/m, and b=200 N- s/m. Write a MATLAB script file that: (a) calculates the natural frequency, damping ratio, and damped natural frequency for the system; and (b) uses the impulse command to find and plot the response of the system to a unit impulse input.arrow_forward
- EXPERIMENT TITLE : PID CONTROLLER IN LEVEL CONTROL SYSTEM OBJECTIVE:To demonstrate the characteristic of P,PI and PID controller response on a level controller system. Based on the topic and objective given,please make a clear introduction.arrow_forwardExample 1.1 Figure 1.5 shows the block diagram of a closed-loop flow control system. Identify the following elements: (a) the sensor, (b) the transducer, (c) the actuator, (d) the transmitter, (e) the controller, (f) the manipulated variable, and (g) the measured variable. In the figure above, the (a) sensor is labeled as the pressure cell. The (b) transducer is labeled as the converter. However, there are two converters: one for converting pressure to current, and another converting current to pressure for operating the actuator. The (c) actuator is labeled as the pneumatic valve. The (d) transmitter is labeled as the line driver. The (e) controller is labeled as the PLC. The (f) manipulated variable is labeled as the pressure developed by the fluid flowing through the orifice plate. The (g) measured variable is the flow rate of the liquid.arrow_forwardThe Gilles & Retzbach model of a distillation column, the system model includes the dynamics of a boiler, is driven by the inputs of steam flow and the flow rate of the vapour side stream, and the measurements are the temperature changes at two different locations along the column.

- Q2 The position of an elevator h(s) is controlled by means of lifting cables. A feedback control system is used to control the force applied by the cables to the elevator. The transfer function of the plant is, 1 Gp(s) = Controller Elevator hr(s) h(s) E(s) G.(s) GP(s) A unit step input is provided. If only proportional control is used, show that the position of the elevator oscillates about the reference value of 1. Find the period (a) of this oscillation. (b) Show that the addition of derivative action to the system can ensure a non- oscillatory response. Find a relation between the derivative and proportional gains that ensures the response is non-oscillatory. (c) When the proportional and derivative gains are set to Kp = 9 and Kd = 6, respectively, find the damping ratio and natural frequency of the system. Derive the time-domain response of the elevator for a unit step input and confirm that it is not oscillatory.arrow_forwardYou are given a linear resonant actuator used for haptic vibration cues in phones - a device that might produce the vibration that happens when you get a notification.
