Closed loop control is a theory of motor control that involves an executive‚ comparator‚ and effector components. The steps in the closed loop schematic diagram starts off with the input (stimuli) which then goes through info processing. the info processing is the executive stage and within this stage there are three different process that occur. The first process is the Stimulus identification‚ which identifies what it is. Then after is the response selection and then follows the response programming

Processes are often called tasks in embedded operating systems. The function of the task or process is something that takes up time‚ as opposed to memory‚ which is ’something that

Feedback loops are critical in maintain homeostasis for organisms. The two kinds of loops are positive and negative. Negative is especially influential in process of homeostasis because of the ability to regulate amounts thus making negative feedback often times an asset. The feedback loops and hormones are both critical for each other to function. The actions of feedback loops and hormones can then change the concentration gradient. The kidney is a vital organ to maintain a proper level of

Chelsea Ferrell Lab 1 Closed-Loop Control According to our book‚ Motor Learning and Performance‚ a closed-loop control is a type of control that involves the use of feedback and the activity of error detection and correction processes to maintain the desired state; used by people to control slow‚ deliberate movements. The book uses a heating and cooling system to illustrate a closed-loop control‚ but a closed-loop control process is actually used for certain types of human performances. For our
