The equations of motion are : (M +m)ẍ+ bẋ+mlθ̈ cos θ −mlθ̇2 sin θ = F (J +ml2)θ̈ +mgl sin θ = −mlẍ cos θ (1) where: • M = 0.5kg is the mass of the cart • m = 0.2kg is the mass of the pendulum • b = 0.1N/m/sec is the coefficient of friction for the cart • l = 0.3m is
Control System Synthesis - PhD Class Handin 1: Temperature control in a heat exchanger 24/09/2020 A chemical reactor called “stirring tank” is depicted below. The top inlet delivers liquid to be mixed in the tank. The tank liquid must be maintained at a constant temperature by varying the amount of steam supplied to the heat exchanger (bottom pipe) via its control valve. Variations in the temperat
