1. Homework 1.1: Cruise control for a car.
Consider the problem in Lecture 1/Example 1.2. Determine appropriate numerical values for this problem. Study open loop control and closed loop control (Proporitonal, Kp) with Matlab/Simulink. Discuss the effect of disturbance on the control.
Fp: Pushing force (from engine)
Fd: Distrubance
Fd=0
Fd=-mgsin

2. Homework 1.2: PID cruise control for a car.
Consider the problem in Lecture 1/Example 1.2. The vehicle mass and viscous damping coefficient and the other system parameters are given below. Determine appropriate numerical Kp, Kd and Ki values for this problem for case a and b according to the stated desired response criteria. Study closed loop control with MatLab/Simulink.
m=1000kg
B=50Ns/m
Ke=45N/deg
Ka=2.5deg/V
Ks=0.36Vs/m
vref=90km/h
Fp: Pushing force (from engine)
Fd: Distrubance
Fd=0
Fd=-mgsin
Desired response criteria:
-Overshoot should be less than %10
-Steady state error should be less than %2
-tss settling time should be less than 5 seconds.
a) For =0° determine Kp, Kd and Ki parameters
b) For =5° determine Kp, Kd and Ki parameters
Note: Operating voltage of sensor and actuator is between 0-24V.
The vehicle can reach at most the speed of 240km/h.
