Modern control design with matlab and simulink

1. ¿What is Control?

   • act of producing a desired result
     • control all artificial processes
       • Control system
         • artificial
           • Refrigerator
           • TV
           • Car
           • Movil
           • Micro Wave Oven
           • Etc.
         • Natural Environment
           • Composition
           • Temperature
           • pressure atm.
           • Metabolism of all living organisms
           • Etc.
         • Developing a mathematical model for each component of the control system.
           • plant
             • controller block
               • Human
               • Artificial device
               • Input
             • output
               • Measurable output
         • The human body
           • while sleeping
             • the brain regulates
               • body temperature
               • heartbeat
               • blood-pressure

2. ¿ what different varieties of control systems there are?

   • Open-Loop
     • Sistemta de control
       • input
         • Controller block
           • plant
             • ouput
               • The result is unlikely to be successful
       • transfer-function
         • Affected by physical factors or natural
   • Closed-Loop
     • Control system
       • input
         • Error + -
           • controller block
             • plant
               • output
                 • Feedback loup
           • Arithmetic sum
             • u(t)
               • yd-y=0
                 • System is stable
       • Transfer-function
   • Other classification of control systems
     • Set the status of the system
       • stochastic system
         • Static
           • System that are not deterministic
             • has no laws governing it
       • Deterministic system
         • Information of the physical quantities
           • physical laws
             • initial conditions
             • linear algebraic or not linear
               • Differential equations
                 • Partial
                   • Distributed parameter system
                 • ordinary
                   • Lumped parameter system
       • Chaotic control system
         • change in the initial conditions
           • Change in the system state at a later time
             • Any unpredictable system
     • Also classified based
       • SISO
       • MISO
       • SIMO
       • MIMO
     • Based
       • characteristics
       • Stability
       • Controllability
       • Observability
       • Etc
     • Outputs are continuous or discontinuous in time
       • Differental equations
         • As a continuous function of time
           • Assumption
             • Digital system can be approximated an analogic system

3. On the Road to Control System Analysis and Design

   • unknown control system
     • apply some well known inputs
       • carefully observe how it responds

4. Matlab, Simulink and the control system toolbox

   • linear algebraic operations required in modern control design
     • use of standard programming techniques
       • MATLAB®
         • solving problems in control
   • integration of linear or nonlinear governing differential equations
   • modeling control systems, and simulating of control systems
     • SIMULINK®
       • Graphical Users Interface
         • It lets you work directly with the block-diagrams
           • designing and analyzing control systems
           • Without the use of equaciones mathematics
