I got a plant and a controller which controlling the plant. Before the control signals go into the plant transfer function,it have to pass through saturation +-0.1. We can do this easily in Simulink by dragging and make used of the saturation function block. Instead of using the Simulink, do anyone know how to type the saturation command in Matlab command window?

在 MATLAB Online 中打开

saturated_x = min(0.1, max(-0.1, x));

You could do it in MATLAB but I would recommend modeling nonlinear control systems, including control saturation effects in Simulink. Simulink was designed to make modeling and simulation of such systems easy. In MATLAB you would need to write code that would solve ordinary differential equations describing dynamics of your plant and your controller one time step at a time. You would have to write ODE solver yourself using a for loop, or you can use ode45 function in MATLAB and write your own implementation of odefun argument that would have to account for saturation.
