SYSC3600B - Lab 3 Control of an Inverted Pendulum Nicholas Nemec 101211060 12/1/2023
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. 2: Controller Design Figure 1: Inverted pendulum system[Lab Manual]
Figure 2: Simulink model to simulate the zero-input response of the inverted pendulum and the cart[Lab Manual] Figure 3: Simulink model that implements the PD controller to simulate the non-linear dynamics of the cart/pendulum[Lab Manual]
Figure 4: Simulink subsystem that implements the non-linear dynamics of the angle of the pendulum Θ o (t) and the position of the cart x(t)[Lab Manual]
3: Pre-Lab Transfer function of the system: 𝐻(?) = Θ ? (?) Θ ? (?) = 𝐵 ? 2 + ? ? ?? ?+[ ? ? −(?+?)? ?? ] General transfer function: 𝐻(?) = ? ? 2 +2ζω ? 2 ? 2 Using the given values, M=1000 kg, m=200 kg, l=10 m, ω n =0.5 rad/sec, ζ=0.7 and g=9.81 m/s 2 , the values of k p and k d were calculated to be:
